A tumor‐related protein, human chromosome 7 ORF 24 (C7orf24), is involved in regulation of the glutathione homeostasis cycle as a γ‐glutamyl cyclotransferase (GGCT). The singular substrate preference of this enzyme had long hampered its chemical probe development. That is, substrate of GGCT is definitely ‘γ‐Glu‐Xaa’, where Xaa is an L‐α‐amino acid. Based on the structure of substrates and GGCT fluorogenic
肿瘤相关蛋白人类染色体7 ORF 24(C7orf24)作为γ-谷氨酰环转移酶(GGCT)参与谷胱甘肽稳态循环的调控。这种酶对底物的偏爱早就阻碍了其化学探针的发展。也就是说,GGCT的底物肯定是“ γ -Glu-Xaa”,其中Xaa是L - α-氨基酸。根据底物和GGCT荧光探针LISA-4 / 101的结构,我们成功开发了一种荧光标记的抑制剂gKFA。这些化学工具将在将来协助癌症相关的研究。版权所有©2017欧洲多肽协会和John Wiley&Sons,Ltd.
