Function
ATSK_MYCTU Alpha-ketoglutarate-dependent sulfate ester dioxygenase, which oxidizes medium-chain alkyl-sulfate esters (PubMed:23762287). Shows preference for 2-ethylhexyl sulfate (2-EHS) in vitro, leading to the formation of succinate and 2-ethylhexanal (PubMed:23762287, PubMed:25427196). Has likely a role in sulfate scavenging in vivo (PubMed:23762287).[1] [2] Also causes the inactivation of the 2-carboxyquinoxaline Ty38c (an antitubercular compound that inhibits DprE1) via oxidative decarboxylation, using Ty38c instead of alpha-ketoglutarate as a substrate. Is thus responsible for primary resistance of M.tuberculosis to Ty38c in vitro. Overexpression of Rv3406 causes resistance to Ty38c.[3]
