Reaction: acetyl-CoA + H2O + 3-(hydroxyphosphinoyl)pyruvate = phosphinomethylmalate + CoA
Other name(s): pmmS (gene name)
Systematic name: acetyl-CoA:phosphinopyruvate C-acetyltransferase (thioester-hydrolysing, phosphinomethylmalate-forming)
Comments: The enzyme, characterized from the bacterium Streptomyces hygroscopicus, participates in the pathway for bialaphos biosynthesis. It requires a divalent metal ion and can also act on oxaloacetate.
