2.1.1.281 |
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. |
