Protein

Aromatic-amino-acid aminotransferase

Gene

tyrB

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Broad-specificity enzyme that catalyzes the transamination of 2-ketoisocaproate, p-hydroxyphenylpyruvate, and phenylpyruvate to yield leucine, tyrosine, and phenylalanine, respectively. In vitro, is able to catalyze the conversion of beta-methyl phenylpyruvate to the nonproteinogenic amino acid (2S,3S)-beta-methyl-phenylalanine, a building block of the antibiotic mannopeptimycin produced by Streptomyces hygroscopicus NRRL3085.1 Publication

Catalytic activityi

An aromatic amino acid + 2-oxoglutarate = an aromatic oxo acid + L-glutamate.1 Publication
(2S,3S)-3-methylphenylalanine + 2-oxoglutarate = (3S)-2-oxo-3-phenylbutanoate + L-glutamate.1 Publication

Cofactori

Pyridoxal phosphate.
