Cadystins induced in a fission yeast treated with Cd2+ are the higher homologs of glutathione. In the present work, glutathione was incubated with Carboxypeptidase Y at a high substrate concentration. The reaction afforded not only the degraded product, but also cadystins and their analogs. A possible transformation pathway for glutathione by this enzyme is proposed.
镉处理的分裂酵母中诱导产生的镉素是谷胱甘肽的高级同源物。在本研究中,谷胱甘肽在高底物浓度下与羧肽酶 Y 共同孵育。反应不仅产生了降解产物,还生成了镉素及其类似物。据此,我们提出了一种谷胱甘肽通过该酶可能的转化途径。
