Ko nga γ-Glutamyltranspeptidases (γ-GTs) ka wehe i te here γ-glutamyl amide o te glutathione me te whakawhiti i te roopu γ-glutamyl i tukuna ki te wai (hydrolysis) ranei te waikawa amino acceptor (transpeptidation).He mahi nui enei enzyme ki nga waahi katoa i roto i te koiora me te whakahekenga o te glutathione, me te whakakorenga o te xenobiotic.I konei ka ripoatahia e matou te hanganga karaihe taumira 3Å o Bacillus licheniformis γ-GT (BlGT) me tona matatini me te l-Glu.Ko nga hanganga hihi-X e whakau ana ko te BlGT no roto i te N-terminal nucleophilic hydrolase superfamily me te whakaatu kei te pūmua he kowhatu waahi kaha e tuwhera ana he rite ki te korero mo te enzyme homologous mai i Bacillus subtilis, engari he rereke mai i nga mea i kitea mo te γ-GT tangata me mo nga γ-GT mai i etahi atu microorganisms.Ko nga raraunga e kii ana ko te herenga o te l-Glu e whakaohooho ana i te hiku C-terminal o BlGT waahanga nui me te tuku i te tautuhi i te huinga o nga toenga waikawa ka uru pea ki te mohiotanga o te katote whakarewa.Ko te mahi o enei toenga i runga i te whakapumautanga o te BlGT kua rangahaua ma te tohu i te tukatuka aunoa, te mahi enzymatic, te matū me te waiariki denaturation o nga mutants Ala hou e wha.Ko nga hua e whakaatu ana ko te whakakapi i te Asp568 me te Ala ka pa ki te tukatuka aunoa me te pumau o te hanganga o te pūmua.
