| Comments | In most cases, AON synthase activity has been tested with pimeloyl-CoA as substrate, however it is believed that pimeloyl-ACP rather than pimeloyl-CoA is the physiological substrate of BioF (PubMed:20693992). BioF (8-amino-7-oxononanoate synthase)(TIGR00858) and Kbl (2-amino-3-ketobutyrate coenzyme A ligase)(TIGR01822) catalyze very close reactions, and alignment of the amino acid sequences of both enzymes reveals a very close homology, which does not allow to separate them. The only way to create a specific family for the BioF enzymes is to limit the rule to Pseudomonadota. A few Bacillota (LYSSH and some close orthologs), are annotated as a 8-amino-7-oxononanoate synthase (BioF) due to their characterisation but are not members of the family. The rest of proteins which cannot be differentiated, is annotated as a putative 8-amino-7-oxononanoate synthase in DE line and are not members of the family. Proteins with both activites (TIGR00858/TIGR01825) are annotated as putative 8-amino-7-oxononanoate synthase/2-amino-3-ketobutyrate coenzyme A ligase in DE lines and BIKB in ID lines. |
