EC 22.214.171.124 Enzyme
Acting on carbon-phosphorus bonds;
Acting on carbon-phosphorus bonds (only sub-subclass identified to date)
3-phosphonopyruvate + H2O = pyruvate + phosphate [RN:
Highly specific for phosphonopyruvate as substrate . The reaction is not inhibited by phosphate but is inhibited by the phosphonates phosphonoformic acid, hydroxymethylphosphonic acid and 3-phosphonopropanoic acid . The enzyme is activated by the divalent cations Co2+, Mg2+ and Mn2+. This enzyme is a member of the phosphoenolpyruvate mutase/isocitrate lyase superfamily .
