Gamma-glutamylcyclotransferase (GGCT) catalyzes the formation of 5-oxoproline from gamma-glutamyl dipeptides, the penultimate step in glutathione catabolism, and may play a critical role in glutathione homeostasis. GGCT may also play a role in cell proliferation, and the expression of GGCT is a potential marker for cancer [taken from NCBI Entrez Gene (Gene ID: 79017)].
