Glutamine-phenylpyruvate transaminase

In enzymology, a glutamine-phenylpyruvate transaminase (EC number|2.6.1.64) is an enzyme that catalyzes the chemical reaction

:L-glutamine + phenylpyruvate $ightleftharpoons$ 2-oxoglutaramate + L-phenylalanine

Thus, the two substrates of this enzyme are L-glutamine and phenylpyruvate, whereas its two products are 2-oxoglutaramate and L-phenylalanine.

This enzyme belongs to the family of transferases, specifically the transaminases, which 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. It employs one cofactor, pyridoxal phosphate.

tructural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB link|1YIY and PDB link|1YIZ.
