Gamma-glutamylcyclotransferase
In enzymology, a gamma-glutamylcyclotransferase is an enzyme that catalyzes the chemical reaction
Hence, this enzyme has one substrate, -L-amino acid, and two products, 5-oxoproline and L-amino acid.
This enzyme belongs to the family of transferases, specifically the aminoacyltransferases. The systematic name of this enzyme class is -L-amino-acid 5-glutamyltransferase . Other names in common use include gamma-glutamyl-amino acid cyclotransferase, gamma-L-glutamylcyclotransferase, and L-glutamic cyclase. This enzyme participates in glutathione metabolism.As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and.
