Description | Gamma-glutamyl cyclotransferase (GGCT) catalyzes the formation of pyroglutamic acid (5-oxoproline) from dipeptides containing gamma-glutamyl, and is a dimeric protein. In Homo sapiens, the protein is encoded by the gene C7orf24 [ ]. The enzyme participates in the gamma-glutamyl cycle, which plays a pre-eminent role in glutathione homoeostasis []. The synthesis and metabolism of glutathione (L-gamma-glutamyl-L-cysteinylglycine) ties the gamma-glutamyl cycle to numerous cellular processes; glutathione acts as a ubiquitous reducing agent in reductive mechanisms involved in protein and DNA synthesis, transport processes, enzyme activity, and metabolism.AIG2 (avrRpt2-induced gene) is an Arabidopsis protein that exhibits RPS2- and avrRpt2-dependent induction early after infection with Pseudomonas syringae pv maculicola strain ES4326 carrying avrRpt2 [ , ]. avrRpt2 is an avirulence gene that can convert virulent strains of P. syringae to avirulence on Arabidopsis thaliana, soybean, and bean. This GGCT-like domain is also found in bacterial tellurite-resistance proteins (TrgB) [], butirosin biosynthesis protein BtrG [], and in proteins described as ChaC, involved in a novel pathway for glutathione degradation []. |
