Enzyme Information
| 2.6.1.57 |
Aromatic-amino-acid transaminase.
based on mapping to UniProt P04693
An aromatic amino acid + 2-oxoglutarate = an aromatic oxo acid + L-glutamate.
-!- L-methionine can also act as donor, more slowly. -!- Oxaloacetate can act as acceptor. -!- Controlled proteolysis converts the enzyme to EC 2.6.1.1.
|
| 2.6.1.107 |
Beta-methylphenylalanine transaminase.
based on mapping to UniProt P04693
(2S,3S)-3-methylphenylalanine + 2-oxoglutarate = (3S)-2-oxo-3- phenylbutanoate + L-glutamate.
-!- Isolated from the bacterium Streptomyces hygroscopicus NRRL3085. -!- It is involved in the biosynthesis of the glycopeptide antibiotic mannopeptimycin.
