ENZYME: 3.11.1.3

Entry

EC 3.11.1.3                 Enzyme

Name

phosphonopyruvate hydrolase;
PPH

Class

Hydrolases;
Acting on carbon-phosphorus bonds;
Acting on carbon-phosphorus bonds (only sub-subclass identified to date)

Reaction(IUBMB)

3-phosphonopyruvate + H2O = pyruvate + phosphate [RN:R08200]

Reaction(KEGG)

R08200

Substrate

3-phosphonopyruvate [CPD:C02798];
H2O [CPD:C00001]

Product

pyruvate [CPD:C00022];
phosphate [CPD:C00009]

Comment

Highly specific for phosphonopyruvate as substrate [2]. The reaction is not inhibited by phosphate but is inhibited by the phosphonates phosphonoformic acid, hydroxymethylphosphonic acid and 3-phosphonopropanoic acid [2]. The enzyme is activated by the divalent cations Co2+, Mg2+ and Mn2+. This enzyme is a member of the phosphoenolpyruvate mutase/isocitrate lyase superfamily [3].
