Glutamine-phenylpyruvate transaminase () is a pyridoxal phosphate-dependent enzyme that catalyzes the chemical reaction
The two substrates of this enzyme characterised from rat kidney are L-glutamine and phenylpyruvic acid. Its products are 2-oxoglutaramic acid and L-phenylalanine.
This enzyme is a transferase, specifically a transaminase, that transfer nitrogenous groups. The systematic name of this enzyme class is L-glutamine:phenylpyruvate aminotransferase. Other names in common use include glutamine transaminase K, and glutamine-phenylpyruvate aminotransferase.
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and .
