Suicide inhibition of a-Oxamine Synthase: Structures of the Covalent Adducts of 8-Amino-7-oxonanoate Synthase with trifluoroalanine
Structural highlights
FunctionBIOF_ECOLI Catalyzes the decarboxylative condensation of pimeloyl-[acyl-carrier protein] and L-alanine to produce 8-amino-7-oxononanoate (AON), [acyl-carrier protein], and carbon dioxide. Can also use pimeloyl-CoA instead of pimeloyl-ACP as substrate, but it is believed that pimeloyl-ACP rather than pimeloyl-CoA is the physiological substrate of BioF.[1] Evolutionary ConservationCheck, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe irreversible inhibition of 8-amino-7-oxononanoate synthase by trifluoroalanine involves decarboxylative defluorination of the inhibitor-PLP aldimine followed by attack of the conjugated imine by the amino group of the active site lysine to afford a covalently bound difluorinated intermediate which can subsequently undergo further HF losses and hydrolysis to afford a 2-(pyridoximine phosphate) acetoyl protein adduct.
