To date, more than 130 GSL structures have been identified, mostly derived from the amino acid methionine. The biosynthesis of methionine-derived aliphatic GSLs starts with a side-chain elongation step involving a recursive three-step cyclic process that incorporates a new methylene group into the 2-oxo acid to form a series of elongated 2-oxo acids. Methylthioalkylmalate synthase (MAMS) catalyzes the first committed step in the side-chain elongation of methionine-derived GSLs. The substrate specificity of MAMS with different 2-oxo acids determines whether reaction products of a given cycle enter for an additional round of chain elongation or enter into core GSLs structure formation. Multiple MAMS encoding genes are present in the Brassicaceae species and are known to play a central role in shaping the diverse profile of aliphatic GSLs. We recently established a highly sensitive LC-MS/MS-based methodology that quantifies the MAMS activity by estimating the amount of the next intermediate of the pathway, the 2-malate derivatives. Overall, this chapter describes the protocol for the expression, purification, and steady-state kinetic analysis of the recombinant MAMS protein.","lang":"eng"}],"title":"An LC-MS/MS Assay for Enzymatic Characterization of Methylthioalkylmalate Synthase (MAMS) Involved in Glucosinolate Biosynthesis","date_published":"2022-10-21T00:00:00Z","author":[{"last_name":"Kumar","orcid":"0000-0002-0346-9125","first_name":"Roshan","id":"50e95140-3016-11ec-9e1a-881b648a1367","full_name":"Kumar, Roshan"},{"last_name":"Reichelt","first_name":"Michael","full_name":"Reichelt, Michael"},{"last_name":"Bisht","first_name":"Naveen C.","full_name":"Bisht, Naveen C."}],"oa_version":"None","year":"2022","language":[{"iso":"eng"}],"month":"10","publication":"Biochemical Pathways and Environmental Responses in Plants: Part A","publication_status":"published","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":"       676","alternative_title":["Methods in Enzymology"],"doi":"10.1016/bs.mie.2022.07.019","volume":676,"article_processing_charge":"No","editor":[{"full_name":"Jez, Joseph","first_name":"Joseph","last_name":"Jez"}],"type":"book_chapter","page":"49-69","quality_controlled":"1","publication_identifier":{"isbn":["9780323955614"],"issn":["0076-6879"]},"date_updated":"2023-12-12T08:11:08Z","date_created":"2023-01-16T10:05:13Z","external_id":{"pmid":["36280361"]},"publisher":"Elsevier"}
