| + | == Function == | ||
| + | [https://www.uniprot.org/uniprot/BIRA_ECOLI BIRA_ECOLI] Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon.<ref>PMID:6129246</ref> <ref>PMID:2667763</ref> <ref>PMID:8003500</ref> <ref>PMID:12527300</ref> | ||
