CC -!- FUNCTION: Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a
CC biotin-operon repressor. In the presence of ATP, BirA activates biotin
CC to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA)
CC complex. HoloBirA can either transfer the biotinyl moiety to the biotin
CC carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or
CC bind to the biotin operator site and inhibit transcription of the
CC operon. {ECO:0000256|HAMAP-Rule:MF_00978}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + biotin + L-lysyl-[protein] = AMP + diphosphate + H(+) +
CC N(6)-biotinyl-L-lysyl-[protein]; Xref=Rhea:RHEA:11756, Rhea:RHEA-
CC COMP:9752, Rhea:RHEA-COMP:10505, ChEBI:CHEBI:15378,

CC ChEBI:CHEBI:57586, ChEBI:CHEBI:83144, ChEBI:CHEBI:456215;

CC ECO:0000256|HAMAP-Rule:MF_00978};
CC -!- SIMILARITY: Belongs to the biotin--protein ligase family.
