IUBMB Enzyme Nomenclature


Accepted name: propionate kinase

Reaction: ATP + propanoate = ADP + propanoyl phosphate

Other name(s): PduW; TdcD; propionate/acetate kinase

Systematic name: ATP:propanoate phosphotransferase

Comments: Requires Mg2+. Acetate can also act as a substrate. Involved in the anaerobic degradation of L-threonine in bacteria [1]. Both this enzyme and EC, acetate kinase, play important roles in the production of propanoate [1].
