ID 2.7.8.23 DE carboxyvinyl-carboxyphosphonate phosphorylmutase. AN carboxyphosphonoenolpyruvate phosphonomutase. AN CPEP phosphonomutase. CA 1-carboxyvinyl carboxyphosphonate + H(+) = CA 3-(hydrohydroxyphosphoryl)pyruvate + CO2. CC -!- Catalyzes the transfer and decarboxylation of the CC carboxy(hydroxy)phosphoryl group, HOOC-P(O)(OH)- (phosphoryl being a CC 3-valent group), in the formation of an unusual C-P bond that is CC involved in the biosynthesis of the antibiotic bialaphos.
