In enzymology a gamma-glutamylcyclotransferase (EC 2.3.2.4) is an enzyme that catalyzes the chemical reaction(5-L-glutamyl)-L-amino acid 5-oxoproline + L-amino acidHence this enzyme has one substrate (5-L-glutamyl)-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 (5-L-glutamyl)-L-amino-acid 5-glutamyltransferase (cyclizing).
