| birA | ribD | STM4138 | STM0416 | biotin-[acetylCoA carboxylase] holoenzyme synthetase; 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.
