IntEnz Enzyme Nomenclature


Accepted name:
[acetyl-CoA carboxylase] kinase
Other names:
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
I-peptide kinase
acetyl-CoA carboxylase kinase (AMP-activated)
Systematic name:
ATP:[acetyl-CoA carboxylase] phosphotransferase



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.
