Accepted name: phenylpyruvate C3-methyltransferase
Reaction: S-adenosyl-L-methionine + 3-phenylpyruvate = S-adenosyl-L-homocysteine + (3S)-2-oxo-3-phenylbutanoate
Glossary: 3-phenylpyruvate = 2-oxo-3-phenylpropanoate
(3S)-2-oxo-3-phenylbutanoate = (3S)-β-methyl-phenylpyruvate
Other name(s): phenylpyruvate Cβ-methyltransferase; phenylpyruvate methyltransferase; mppJ (gene name)
Systematic name: S-adenosyl-L-methionine:2-oxo-3-phenylpropanoate C3-methyltransferase
Comments: The enzyme from the bacterium Streptomyces hygroscopicus NRRL3085 is involved in synthesis of the nonproteinogenic amino acid (2S,3S)-β-methyl-phenylalanine, a building block of the antibiotic mannopeptimycin.
