'''Suicide inhibition of a-Oxamine Synthase: Structures of the Covalent Adducts of 8-Amino-7-oxonanoate Synthase with trifluoroalanine'''<br />


==Overview==
==Suicide inhibition of a-Oxamine Synthase: Structures of the Covalent Adducts of 8-Amino-7-oxonanoate Synthase with trifluoroalanine==
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.

== Function ==
[https://www.uniprot.org/uniprot/BIOF_ECOLI BIOF_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.<ref>PMID:20693992</ref>
