Crystal structure of complex between EIIA and a novel pyruvate decarboxylase
Structural highlights
FunctionFRSA_VIBVU Catalyzes the hydrolysis of esters (PubMed:30951551). In vitro, prefers short chain alkanoate ester as substrate. Displays highest activity towards p-nitrophenyl acetate (pNPA). Has weaker activity towards p-nitrophenyl butyrate (pNPB) (PubMed:30951551).[1] Publication Abstract from PubMedThe interaction between fermentation-respiration switch (FrsA) protein and glucose-specific enzyme IIA(Glc) increases glucose fermentation under oxygen-limited conditions. We show that FrsA converts pyruvate to acetaldehyde and carbon dioxide in a cofactor-independent manner and that its pyruvate decarboxylation activity is enhanced by the dephosphorylated form of IIA(Glc) (d-IIA(Glc)). Crystal structures of FrsA and its complex with d-IIA(Glc) revealed residues required for catalysis as well as the structural basis for the activation by d-IIA(Glc). FrsA functions as a cofactor-independent decarboxylase to control metabolic flux.,Lee KJ, Jeong CS, An YJ, Lee HJ, Park SJ, Seok YJ, Kim P, Lee JH, Lee KH, Cha SS Nat Chem Biol. 2011 May 29.
