The 3 substrates of this enzyme are ATP, biotin, and ], whereas its 3 products are AMP, diphosphate, and ].
This enzyme belongs to the family of ligases, specifically those forming generic carbon-nitrogen bonds. The systematic name of this enzyme class is biotin:apo-[acetyl-CoA:carbon-dioxide ligase (ADP-forming)] ligase (AMP-forming). Other names in common use include biotin-[acetyl-CoA carboxylase] synthetase, biotin-[acetyl coenzyme A carboxylase] synthetase, acetyl coenzyme A holocarboxylase synthetase, acetyl CoA holocarboxylase synthetase, biotin:apocarboxylase ligase, Biotin holoenzyme synthetase, and HCS. This enzyme participates in biotin metabolism.
