Suicide inhibition of a-Oxamine Synthase: Structures of the Covalent Adducts of 8-Amino-7-oxonanoate Synthase with trifluoroalanine
Overview
The 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.
About this Structure
2G6W is a Single protein structure of sequence from Escherichia coli with as ligand. Active as 8-amino-7-oxononanoate synthase, with EC number 2.3.1.47 Full crystallographic information is available from OCA.
