以酿酒酵母的几个蛋白酶缺陷型突变株为材料,研究了碳饥饿过程中依赖NADP的谷氨酸脱氢酶(L-谷氨酸:NADP+氧化还原酶,EC 1.4.1.4)的蛋白水解性失活。携带蛋白酶B或蛋白酶C(羧基肽酶Y)结构基因突变的菌株催化NADP-谷氨酸脱氢酶失活和初始蛋白分解的速率与野生型亲本菌株几乎没有区别。此外,导致蛋白酶A、B和C缺失的多效性突变Pep4-3不影响NADP-谷氨酸脱氢酶的失活或初始蛋白分解。
The proteolytic inactivation of NADP-dependent glutamate dehydrogenase (l-glutamate: NADP+oxidoreductase, EC 1.4.1.4) during carbon starvation was studied using several proteinase-deficient mutants ofSaccharomyces cerevisiae. Strains bearing mutations in the structural genes for proteinase B, proteinase C (carboxypeptidase Y), or in both genes catalyzed the inactivation and initial proteolytic cleavage of NADP-glutamate dehydrogenase at a rate indistinguishable from that of the wild-type parent strain. In addition, the pleiotropic mutation,pep4-3, which results in a deficiency for proteinases A, B, and C, did not affect the inactivation or initial proteolytic cleavage of NADP-glutamate dehydrogenase.
