Propionate kinase (EC 2.7.2.15 , PduW , TdcD , propionate/acetate kinase ) is an enzyme with systematic name ATP:propanoate phosphotransferase .[ 1] [ 2] [ 3] [ 4] [ 5] [ 6] This enzyme catalyses the following chemical reaction
ATP + propanoate
⇌
{\displaystyle \rightleftharpoons }
ADP + propanoyl phosphate
This enzyme requires Mg2+ .
