IUBMB Enzyme Nomenclature


Accepted name: [acetyl-CoA carboxylase] kinase

Reaction: ATP + [acetyl-CoA carboxylase] = ADP + [acetyl-CoA carboxylase] phosphate

Other name(s): acetyl coenzyme A carboxylase kinase (phosphorylating); acetyl-CoA carboxylase bound kinase; acetyl-CoA carboxylase kinase; acetyl-CoA carboxylase kinase (cAMP-independent); acetyl-CoA carboxylase kinase 2; acetyl-CoA carboxylase kinase-2; acetyl-CoA carboxylase kinase-3 (AMP-activated); acetyl-coenzyme A carboxylase kinase; ACK2; ACK3; AMPK; I-peptide kinase; STK5

Systematic name: ATP:[acetyl-CoA carboxylase] phosphotransferase

Comments: Phosphorylates and inactivates EC, acetyl-CoA carboxylase, which can be dephosphorylated and reactivated by EC, [phosphorylase] phosphatase. The enzyme is more active towards the dimeric form of acetyl-CoA carboxylase than the polymeric form [5]. Phosphorylates serine residues.
