Accepted name: β-methylphenylalanine transaminase
Reaction: (2S,3S)-3-methylphenylalanine + 2-oxoglutarate = (3S)-2-oxo-3-phenylbutanoate + L-glutamate
Glossary: (3S)-2-oxo-3-phenylbutanoate = (3S)-β-methyl-phenylpyruvate
Other name(s): TyrB
Systematic name: (2S,3S)-3-methylphenylalanine:2-oxoglutarate aminotransferase
Comments: Requires pyridoxal phosphate. Isolated from the bacterium Streptomyces hygroscopicus NRRL3085. It is involved in the biosynthesis of the glycopeptide antibiotic mannopeptimycin.
