EC 2.7.8.23

Accepted name: carboxyvinyl-carboxyphosphonate phosphorylmutase

Reaction: 1-carboxyvinyl carboxyphosphonate = 3-(hydrohydroxyphosphoryl)pyruvate + CO2

Systematic name: 1-carboxyvinyl carboxyphosphonate phosphorylmutase (decarboxylating)

Comments: catalyses the transfer and decarboxylation of the carboxy(hydroxy)phosphoryl group, HOOC-P(O)(OH)- (phosphoryl being a 3-valent group), in the formation of an unusual C-P bond that is involved in the biosynthesis of the antibiotic bialaphos.
