Glutamate degradation IX

In S. cerevisiae cells, the amino group of glutamate and the amide group of glutamine are the source of nitrogen for all other macromolecules. In order to provide ammonia for the synthesis of glutamine during growth on glutamate-yielding nitrogen sources, cells degrade glutamate into ammonia. The main pathway for S. cerevisiae glutamate degradation is catalyzed by the NAD dependent glutamate dehydrogenase (GDH2). Description adapted from on https://pathway.yeastgenome.org/.

在酿酒酵母（S. cerevisiae）细胞中，谷氨酸的氨基基团和谷氨酰胺的酰胺基团构成了所有其他大分子氮源的基础。为了在以谷氨酸为氮源的生长过程中为谷氨酰胺的合成提供氨，细胞将谷氨酸降解为氨。酿酒酵母谷氨酸降解的主要途径由依赖于NAD的谷氨酸脱氢酶（GDH2）催化。描述改编自https://pathway.yeastgenome.org/。
