Continued from EC 2.7.1.151 to EC 2.7.1.179
EC 2.7.2 Phosphotransferases with a carboxy group as acceptor
EC 2.7.3 Phosphotransferases with a nitrogenous group as acceptor
Accepted name: acetate kinase
Reaction: ATP + acetate = ADP + acetyl phosphate
Other name(s): acetokinase; AckA; AK; acetic kinase; acetate kinase (phosphorylating)
Systematic name: ATP:acetate phosphotransferase
Comments: 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 2.3.1.8, phosphate acetyltransferase. Both this enzyme and EC 2.7.2.15, propionate kinase, play important roles in the production of propanoate [9].

Other name(s): aspartokinase; AK; β-aspartokinase; aspartic kinase

This is also the case for two of the four isoenzymes in Arabidopsis thaliana. The equilibrium constant strongly favours the reaction from right to left, i.e. the non-physiological direction of reaction.
