应用
来自假单胞菌属或 γ-谷氨酰基水解酶的羧肽酶 G 已用于研究中评估假单孢氧还蛋白 COOH-末端在 P-450cam（细胞色素 m）羟基化中的作用。来源于假单胞菌属的羧肽酶 G 也被用于研究肺腺癌细胞中一氧化氮通过 NO‑cGMP 信号通路对培美曲塞细胞毒性的产生影响。
生化/生理作用
羧肽酶 G 是溶酶体，巯基依赖性蛋白酶，其逐渐切割 γ-谷氨酰蝶酰多聚-γ-谷氨酸，产生蝶酰-α-谷氨酸（叶酸）和游离谷氨酸。它被认为对 γ-谷氨酰基键具有高度特异性，但对于离去基团的 C-末端氨基酸则不具有高度特异性。该同型二聚体的分子量约为 90kDa。酶被 Zn2+ 离子激活。
单位定义
在 pH7.3，30℃ 下，一个单位的酶每分钟将（+）氨甲蝶呤水解产生 1.0 μmole L-谷氨酸。
外形
含有醋酸钠盐。
