  text: The advantageous characteristics attributed to the 19F nucleus have made it
    a popular target for NMR once again in recent years. Aside from solution NMR,
    an increasing number of studies have been conducted applying solid-state magic-angle-spinning
    NMR to fluorine-labeled samples. Here, the high chemical shift anisotropy and
    strong dipolar couplings can be utilized to get structural insights into proteins
    and measure long distances. Despite increasing popularity and promising benefits,
    the sensitivity of biomolecular 19F MAS NMR often suffers from slow longitudinal
    T1 relaxation and therefore long recycle delays. In this work, we expand paramagnetic
    doping, an approach commonly used to reduce proton T1 relaxation times, to 19F-labeled
    biological samples. We study the effect of Gd(DTPA) and Gd(DTPA-BMA) on 19F and
    13C T1 and T2 relaxation in a [5-19F13C]-tryptophan-labeled protein via 19F-detected
    MAS NMR experiments. The observed paramagnetic relaxation enhancement substantially
    reduces measurement times of 19F MAS NMR experiments without compromising resolution.
    Additionally, we report the chemical-shift assignments of all four fluorotryptophan
    signals in the 12 × 39 kDa large protein using a mutagenesis approach.

  text: "Characterizing protein dynamics at the atomic level is essential for our
    understanding of biological mechanisms. Whether it is to facilitate metabolite
    transport, catalyze reactions, transmit signals, or regulate metabolism – proteins
    are constantly in motion and sample multiple conformational states to fulfill
    their function. Nuclear magnetic resonance (NMR) spectroscopy is particularly
    well suited to elucidate the dynamics of biomolecules on their complex free-energy
    landscape. In particular, solid-state magic-angle spinning (MAS) NMR enables the
    study of large molecular assemblies, protein crystals, or insoluble proteins at
    atomic resolution without an inherent molecular size limitation. MAS NMR experiments
    to probe protein dynamics are extremely versatile and sensitive to motional timescales
    from picoseconds to seconds. Over the past decades, technological advances, developments
    in experimental design, and new isotope-labeling approaches have further expanded
    the possibilities of this technique and significantly improved the accuracy of
    the determined motional parameters.\r\nFunctionally important sites of proteins
    often contain aromatic residues. Their side-chain motions have therefore long
    served as valuable indicators of mechanistically relevant dynamics in NMR studies.
    In this thesis, site-specifically labeled aromatic residues act as sensitive reporters
    for MAS NMR studies of protein dynamics. The first part addresses how different
    environments impact side-chain motion by probing ring flips of phenylalanines
    and tyrosines in crystalline proteins and amyloid fibrils. It provides important
    insights for the analysis of dynamics obtained in non-native protein environments
    and emphasizes the complex factors that determine the timescale of internal dynamics.
    In the second part, the focus shifts towards methodological questions regarding
    the investigation of protein dynamics by 19F MAS NMR. The fluorine nucleus exhibits
    promising characteristics for NMR studies but also presents significant challenges,
    which is why the full methodological potential of 19F MAS NMR has not been fully
    realized yet. This work demonstrates that paramagnetic doping can considerably
    reduce the measurement time and improve the sensitivity of fluorinated samples.
    Finally, 19F MAS NMR is evaluated as a tool for studying protein side-chain dynamics
    on the example of tryptophans. The results illustrate the challenges in analyzing
    such experiments and lay the foundation for further development of 19F MAS NMR
    relaxation studies.\r\nTaken together, this thesis highlights the potential of
    combining specific isotope labeling, MAS NMR, and complementary methods such as
    crystallography and computational simulations to elucidate internal protein dynamics.
    The further development of such integrative approaches will be crucial to improving
    our understanding of complex mechanisms and protein function.\r\n"

  text: Protein conformational energy landscapes are shaped not only by intramolecular
    interactions but also by their environment. In protein crystals and protein–protein
    complexes, intermolecular contacts alter this energy landscape, but the exact
    nature of this alteration is difficult to decipher. Understanding how the crystal
    lattice affects protein dynamics is crucial for crystallography-based studies
    of motion, yet its influence on collective motions remains unclear. Aromatic ring
    flips in the hydrophobic core represent sensitive probes of such dynamics. Here,
    we compare the kinetics of aromatic ring flips in the protein GB1 in crystals,
    in complex with its binding partner IgG, and in solution, combining advanced isotope
    labelling with quantitative NMR methods. We show that rings in the core flip nearly
    a thousand times less frequently in crystals than in solution. Enhanced-sampling
    molecular dynamics simulations, based on a crystal structure of a GB1 variant
    reported in this work, reproduce these elevated barriers and reveal how the crystal
    restrains motions.

  text: 'Protein conformational energy landscapes are shaped not only by intramolecular
    interactions but also by their environment. In protein crystals and protein-protein
    complexes, intermolecular contacts alter this energy landscape, but the exact
    nature of this alteration is difficult to decipher. Understanding how the crystal
    lattice affects protein dynamics is crucial for crystallography-based studies
    of motion, yet its influence on collective motions remains unclear. Aromatic ring
    flips in the hydrophobic core represent sensitive probes of such dynamics. Here,
    we compare the kinetics of aromatic ring flips in the protein GB1 in crystals,
    in complex with its binding partner IgG, and in solution, combining advanced isotope
    labeling with quantitative NMR methods. We show that rings in the core flip nearly
    a thousand times less frequently in crystals than in solution. Enhanced-sampling
    molecular dynamics simulations, based on a new crystal structure, reproduce these
    elevated barriers and reveal how the crystal restrains motions. '

  text: Dynamic processes in molecules can occur on a wide range of timescales, and
    it is important to understand which timescales of motion contribute to different
    parameters used in dynamics measurements. For spin relaxation, this can easily
    be understood from the sampling frequencies of the spectral-density function by
    different relaxation-rate constants. In addition to data from relaxation measurements,
    determining dynamically averaged anisotropic interactions in magic-angle spinning
    (MAS) solid-state NMR allows for better quantification of the amplitude of molecular
    motion. For partially averaged anisotropic interactions, the relevant timescales
    of motion are not so clearly defined. Whether the averaging depends on the experimental
    methods (e.g., pulse sequences) or conditions (e.g., MAS frequency, magnitude
    of anisotropic interaction, radio-frequency field amplitudes) is not fully understood.
    To investigate these questions, we performed numerical simulations of dynamic
    systems based on the stochastic Liouville equation using several experiments for
    recoupling the dipolar coupling, chemical-shift anisotropy or quadrupolar coupling.
    As described in the literature, the transition between slow motion, where parameters
    characterizing the anisotropic interaction are not averaged, and fast motion,
    where the tensors are averaged leading to a scaled anisotropic quantity, occurs
    over a window of motional rate constants that depends mainly on the strength of
    the interaction. This transition region can span 2 orders of magnitude in exchange-rate
    constants (typically in the microsecond range) but depends only marginally on
    the employed recoupling scheme or sample spinning frequency. The transition region
    often coincides with a fast relaxation of coherences, making precise quantitative
    measurements difficult. Residual couplings in off-magic-angle experiments, however,
    average over longer timescales of motion. While in principle one may gain information
    on the timescales of motion from the transition area, extracting such information
    is hampered by low signal-to-noise ratio in experimental spectra due to fast relaxation
    that occurs in the same region.

  text: Aromatic side chains are important reporters of the plasticity of proteins,
    and often form important contacts in protein–protein interactions. We studied
    aromatic residues in the two structurally homologous cross-β amyloid fibrils HET-s,
    and  HELLF by employing a specific isotope-labeling approach and magic-angle-spinning
    NMR. The dynamic behavior of the aromatic residues Phe and Tyr indicates that
    the hydrophobic amyloid core is rigid, without any sign of "breathing motions"
    over hundreds of milliseconds at least. Aromatic residues exposed at the fibril
    surface have a rigid ring axis but undergo ring flips on a variety of time scales
    from nanoseconds to microseconds. Our approach provides direct insight into hydrophobic-core
    motions, enabling a better evaluation of the conformational heterogeneity generated
    from an NMR structural ensemble of such amyloid cross-β architecture.

  text: Aromatische Seitenketten sind wichtige Indikatoren für die Plastizität von
    Proteinen und bilden oft entscheidende Kontakte bei Protein‐Protein‐Wechselwirkungen.
    Wir untersuchten aromatische Reste in den beiden strukturell homologen cross‐β
    Amyloidfibrillen HET‐s und HELLF mit Hilfe eines spezifischen Ansatzes zur Isotopenmarkierung
    und Festkörper NMR mit Drehung am magischen Winkel. Das dynamische Verhalten der
    aromatischen Reste Phe und Tyr deutet darauf hin, dass der hydrophobe Amyloidkern
    starr ist und keine Anzeichen von “atmenden Bewegungen” auf einer Zeitskala von
    Hunderten von Millisekunden zeigt. Aromatische Reste, die exponiert an der Fibrillenoberfläche
    sitzen, haben zwar eine starre Ringachse, weisen aber Ringflips auf verschiedenen
    Zeitskalen von Nanosekunden bis Mikrosekunden auf. Unser Ansatz bietet einen direkten
    Einblick in die Bewegungen des hydrophoben Kerns und ermöglicht eine bessere Bewertung
    der Konformationsheterogenität, die aus einem NMR‐Strukturensemble einer solchen
    Cross‐β‐Amyloidstruktur hervorgeht.

  text: Aromatic side chains are important reporters of the plasticity of proteins,
    and often form important contacts in protein--protein interactions. By studying
    a pair of structurally homologous cross-β amyloid fibrils, HET-s and HELLF, with
    a specific isotope-labeling approach and magic-angle-spinning (MAS) NMR, we have
    characterized the dynamic behavior of Phe and Tyr aromatic rings to show that
    the hydrophobic amyloid core is rigid, without any sign of "breathing motions"
    over hundreds of milliseconds at least. Aromatic residues exposed at the fibril
    surface have a rigid ring axis but undergo ring flips, on a variety of time scales
    from ns to µs. Our approach provides direct insight into hydrophobic-core motions,
    enabling a better evaluation of the conformational heterogeneity generated from
    a NMR structural ensemble of such amyloid cross-β architecture.

  text: 'Probing the dynamics of aromatic side chains provides important insights
    into the behavior of a protein because flips of aromatic rings in a protein’s
    hydrophobic core report on breathing motion involving a large part of the protein.
    Inherently invisible to crystallography, aromatic motions have been primarily
    studied by solution NMR. The question how packing of proteins in crystals affects
    ring flips has, thus, remained largely unexplored. Here we apply magic-angle spinning
    NMR, advanced phenylalanine 1H-13C/2H isotope labeling and MD simulation to a
    protein in three different crystal packing environments to shed light onto possible
    impact of packing on ring flips. The flips of the two Phe residues in ubiquitin,
    both surface exposed, appear remarkably conserved in the different crystal forms,
    even though the intermolecular packing is quite different: Phe4 flips on a ca.
    10–20 ns time scale, and Phe45 are broadened in all crystals, presumably due to
    µs motion. Our findings suggest that intramolecular influences are more important
    for ring flips than intermolecular (packing) effects.'

  text: Magic-angle spinning (MAS) nuclear magnetic resonance (NMR) is establishing
    itself as a powerful method for the characterization of protein dynamics at the
    atomic scale. We discuss here how R1ρ MAS relaxation dispersion NMR can explore
    microsecond-to-millisecond motions. Progress in instrumentation, isotope labeling,
    and pulse sequence design has paved the way for quantitative analyses of even
    rare structural fluctuations. In addition to isotropic chemical-shift fluctuations
    exploited in solution-state NMR relaxation dispersion experiments, MAS NMR has
    a wider arsenal of observables, allowing to see motions even if the exchanging
    states do not differ in their chemical shifts. We demonstrate the potential of
    the technique for probing motions in challenging large enzymes, membrane proteins,
    and protein assemblies.
