I-γ-Glutamyltranspeptidases (γ-GTs) iqhawula i-γ-glutamyl amide bond ye-glutathione kwaye idlulisele iqela elikhutshiweyo le-γ-glutamyl kumanzi (i-hydrolysis) okanye i-amino acids eyamkelekileyo (transpeptidation).Ezi enzymes zifumaneka kuyo yonke indawo zidlala indima ephambili kwi-biosynthesis kunye nokuthotywa kwe-glutathione, kunye ne-xenobiotic detoxification.Apha sixela i-3Å isisombululo sekristale isakhiwo se-Bacillus licheniformis γ-GT (BlGT) kunye neso bunzima bayo kunye ne-l-Glu.Ulwakhiwo lweX-reyi luqinisekisa ukuba i-BlGT yeye-N-terminal nucleophilic hydrolase superfamily kwaye ityhila ukuba iproteni inendawo evulekileyo ecandekileyo ecandekileyo efana naleyo ibixelwe kwi-enzyme ye-homologous evela kwi-Bacillus subtilis, kodwa yahlukile kwezo zijongwe ngabantu γ-GT kunye ye-γ-GTs evela kwezinye ii-microorganisms.Idatha icebisa ukuba ukubophelela kwe-l-Glu kubangela ukucwangciswa kwakhona kwe-C-terminal umsila we-BlGT enkulu kunye nokuvumela ukuchongwa kweqela leentsalela ze-asidi ezinokuthi zibandakanyeke ekuqapheliseni i-ion yensimbi.Indima yezi ntsalela kuzinzo oluhambelanayo lwe-BlGT iye yaphononongwa ngokubonakalisa i-autoprocessing, umsebenzi we-enzymatic, iikhemikhali kunye ne-thermal denaturation ye-Ala enye entsha eguqulweyo.Iziphumo zibonisa ukuba ukutshintshwa kwe-Asp568 nge-Ala kuchaphazela ukusetyenzwa ngokuzenzekelayo kunye nozinzo lweprotheyini.
