I-γ-Glutamyltranspeptidases (γ-GTs) ihlukanisa ibhondi ye-γ-glutamyl amide ye-glutathione futhi idlulisele iqembu elikhululiwe le-γ-glutamyl emanzini (hydrolysis) noma ama-amino acid owamukelayo (transpeptidation).Lawa ma-enzyme atholakala yonke indawo adlala indima ebalulekile ekwenziweni kwe-biosynthesis kanye nokuwohloka kwe-glutathione, nasekukhipheni ubuthi be-xenobiotic.Lapha sibika ukwakheka kwekristalu kwe-3Å kwe-Bacillus licheniformis γ-GT (BlGT) kanye nalokho okuyinkimbinkimbi yayo ene-l-Glu.Izakhiwo ze-X-ray ziqinisekisa ukuthi i-BlGT ingeyomndeni omkhulu we-N-terminal nucleophilic hydrolase futhi iveza ukuthi iphrotheni inendawo evulekile evulekayo efana naleyo ebikwe i-enzyme ye-homologous evela ku-Bacillus subtilis, kodwa ehlukile kulawo aqashelwa i-γ-GT yomuntu kanye. ama-γ-GT avela kwamanye ama-microorganisms.Idatha iphakamisa ukuthi ukuboshwa kwe-l-Glu kudala ukuhleleka kabusha komsila we-C weyunithi enkulu ye-BlGT futhi kuvumela ukukhonjwa kweqoqo lezinsalela ze-asidi okungenzeka zihileleke ekubonweni kwe-ion yensimbi.Indima yalezi zinsalela ekuzinzeni kokuvumelana kwe-BlGT iye yacutshungulwa ngokufaka uphawu lokucutshungulwa ngokuzenzakalela, umsebenzi we-enzymatic, amakhemikhali kanye nokushintshashintsha kwe-thermal kwezishintshayo ezine ze-Ala eyodwa.Imiphumela ibonisa ukuthi ukushintshwa kwe-Asp568 nge-Ala kuthinta kokubili ukucubungula ngokuzenzakalela kanye nokuzinza kwesakhiwo sephrotheni.
