D-4-hydroxyphenylglycine transaminase () is a pyridoxal phosphate-dependent enzyme that catalyzes the chemical reaction
The two substrates of this enzyme haracterised from Pseudomonas putida are D-4-hydroxyphenylglycine and α-ketoglutaric acid. Its products are 4-hydroxyphenylglyoxylic acid and L-glutamic acid.
This enzyme is a transferase, specifically a transaminase, which transfer nitrogenous groups. The systematic name of this enzyme class is D-4-hydroxyphenylglycine:2-oxoglutarate aminotransferase. This enzyme is also called D-hydroxyphenylglycine aminotransferase.
