ID 4.2.1.166 DE phosphinomethylmalate isomerase. CA phosphinomethylmalate = phosphinomethylisomalate. CC -!- The enzyme, characterized from the bacterium Streptomyces CC viridochromogenes, is involved in bialaphos biosynthesis. CC -!- The enzyme from the bacterium Kitasatospora phosalacinea participates CC in the biosynthesis of the related compound phosalacine. CC -!- Both compounds contain the nonproteinogenic amino acid CC L-phosphinothricin that acts as a potent inhibitor of EC 6.3.1.2. CC -!- The similar enzyme EC 4.2.1.3 cannot catalyze this reaction. //
