Glutamine—phenylpyruvate transaminase
Template:Infobox enzyme In enzymology, a glutamine-phenylpyruvate transaminase (Template:EC number) is an enzyme that catalyzes the chemical reaction
- L-glutamine + phenylpyruvate 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, to be specific, the transaminases, 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. It employs one cofactor, pyridoxal phosphate.
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes Template:PDB link and Template:PDB link.
