EC - Acetate kinase

IntEnz Enzyme Nomenclature


Accepted name:
acetate kinase
Other names:
acetic kinase
acetate kinase (phosphorylating)
Systematic name:
ATP:acetate phosphotransferase




Requires Mg2+ for activity. While purified enzyme from Escherichia coli is specific for acetate [4], others have found that the enzyme can also use propanoate as a substrate, but more slowly [7]. Acetate can be converted into the key metabolic intermediate acetyl-CoA by coupling acetate kinase with EC, phosphate acetyltransferase. Both this enzyme and EC, propionate kinase, play important roles in the production of propanoate [9].
