'''Acetyl-CoA carboxylase''' (ACC) catalyzes the irreversible carboxylation of acetyl-CoA to malonyl-CoA. Malonyl-CoA is a building block in in the biosynthesis of fatty acids. ACC is biotin- and ATP-dependent enzyme. ACC is a multi-subunit enzyme. Each subunit catalyzes different reaction. These are – biotin carboxylase (BC) which carboxylates the biotin prosthetic group see [[Biotin carboxylase]], biotin carboxyl carrier protein (BCCP) which is linked covalently to biotin and carboxyltransferase (CT) which transfers the carboxyl group from biotin to acetyl-CoA. In mammals, 2 forms of ACC exist. ACC1 and ACC2 differ in their tissue distribution and function. | '''Acetyl-CoA carboxylase''' (ACC) catalyzes the irreversible carboxylation of acetyl-CoA to malonyl-CoA.

Acetyl-CoA carboxylase (ACC) catalyzes the irreversible carboxylation of acetyl-CoA to malonyl-CoA. Malonyl-CoA is a building block in in the biosynthesis of fatty acids. ACC is biotin- and ATP-dependent enzyme. ACC is a multi-subunit enzyme. Each subunit catalyzes different reaction. These are – biotin carboxylase (BC) which carboxylates the biotin prosthetic group see Biotin carboxylase, biotin carboxyl carrier protein (BCCP) which is linked covalently to biotin and carboxyltransferase (CT) which transfers the carboxyl group from biotin to acetyl-CoA. In mammals, 2 forms of ACC exist. ACC1 and ACC2 differ in their tissue distribution and function.
