Protein

8-amino-7-oxononanoate synthase

Gene

bioF

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.2 Publications

Catalytic activityi

Pimeloyl-[acyl-carrier protein] + L-alanine = 8-amino-7-oxononanoate + CO2 + holo-[acyl-carrier protein].2 Publications

Cofactori

pyridoxal 5'-phosphate1 Publication

Enzyme regulationi

Competitively inhibited by D-alanine, 8-amino-7-hydroxy-8-phosphonononanoic acid and 2-amino-3-hydroxy-2-methylnonadioic acid.1 Publication

Kineticsi
