Here we show that, even under physiological conditions, dGTP is largely overrepresented among other dNTPs in mitochondria of mouse tissues and human cultured cells. In addition, a vast majority of mitochondrial dGTP is tightly bound to NDUFA10, an accessory subunit of complex I of the mitochondrial respiratory chain. NDUFA10 shares a deoxyribonucleoside kinase (dNK) domain with deoxyribonucleoside kinases in the nucleotide salvage pathway, though no specific function beyond stabilizing the complex I holoenzyme has been described for this subunit. We mutated the dNK domain of NDUFA10 in human HEK-293T cells while preserving complex I assembly and activity. The NDUFA10E160A/R161A shows reduced dGTP binding capacity in vitro and leads to a 50% reduction in mitochondrial dGTP content, proving that most dGTP is directly bound to the dNK domain of NDUFA10. This interaction may represent a hitherto unknown mechanism regulating mitochondrial dNTP availability and linking oxidative metabolism to DNA maintenance.","lang":"eng"}],"quality_controlled":"1","doi":"10.1038/s42003-022-03568-6","citation":{"mla":"Molina-Granada, David, et al. “Most Mitochondrial DGTP Is Tightly Bound to Respiratory Complex I through the NDUFA10 Subunit.” <i>Communications Biology</i>, vol. 5, no. 1, 620, Springer Nature, 2022, doi:<a href=\"https://doi.org/10.1038/s42003-022-03568-6\">10.1038/s42003-022-03568-6</a>.","ista":"Molina-Granada D, González-Vioque E, Dibley MG, Cabrera-Pérez R, Vallbona-Garcia A, Torres-Torronteras J, Sazanov LA, Ryan MT, Cámara Y, Martí R. 2022.
