Hoʻokaʻawale ʻo γ-Glutamyltranspeptidases (γ-GTs) i ka paʻa γ-glutamyl amide o ka glutathione a hoʻololi i ka hui γ-glutamyl i hoʻokuʻu ʻia i ka wai (hydrolysis) a i ʻole nā ʻakika amino acceptor (transpeptidation).ʻO kēia mau enzymes ubiquitous ke kuleana nui i ka biosynthesis a me ka degradation o glutathione, a me ka detoxification xenobiotic.Maʻaneʻi mākou e hōʻike nei i ka 3Å hoʻonā aniani hoʻonā o Bacillus licheniformis γ-GT (BlGT) a me kona paʻakikī me l-Glu.Hōʻoia nā hale X-ray e pili ana ʻo BlGT i ka N-terminal nucleophilic hydrolase superfamily a hōʻike ʻia aia ka pūmua i ka wehe ʻana o ka wahi hana e like me ka mea i hōʻike ʻia no ka enzyme homologous mai Bacillus subtilis, akā ʻokoʻa i nā mea i ʻike ʻia no ke kanaka γ-GT a no nā γ-GT mai nā microorganism ʻē aʻe.Hōʻike ka ʻikepili i ka hoʻopaʻa ʻana o ka l-Glu i ka hoʻonohonoho hou ʻana o ka huelo C-terminal o BlGT subunit nui a ʻae i ka ʻike ʻana i kahi pūʻulu o nā koena waikawa i komo i ka ʻike ʻana i kahi ion metala.Ua aʻo ʻia ke kuleana o kēia mau koena ma ka conformational stability o BlGT ma ke ʻano o ka autoprocessing, hana enzymatic, kemika a me ka thermal denaturation o ʻehā mau mutants Ala hou.Hōʻike nā hopena i ka hoʻololi ʻana o Asp568 me kahi Ala e pili ana i ka autoprocessing a me ka paʻa o ka protein.
