KEGG   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].
