Enzyme Information

2.1.1.281

Phenylpyruvate C(3)-methyltransferase.

based on mapping to UniProt Q643C8

S-adenosyl-L-methionine + 3-phenylpyruvate = S-adenosyl-L-homocysteine + (3S)-2-oxo-3-phenylbutanoate.

-!- The enzyme from the bacterium Streptomyces hygroscopicus NRRL3085 is involved in synthesis of the nonproteinogenic amino acid (2S,3S)- beta-methyl-phenylalanine, a building block of the antibiotic mannopeptimycin.
