一般描述

L-精氨酸酶也称为L-精氨酸氨基水解酶。它具有两种形式,如精氨酸酶-1和精氨酸酶-2。精氨酸酶1存在于肝细胞中,精氨酸酶2通常存在于肝外组织,如肾脏、大脑、骨骼肌、小肠和哺乳期乳腺。精氨酸酶-2位于人染色体14q24.1−24.3上。

生化/生理作用

L-精氨酸酶将L-精氨酸水解为L-鸟氨酸和尿素,这是排尿素物种的肝脏中尿素循环的最后一步。精氨酸酶在哺乳动物免疫系统中发挥主要作用,并且参与炎症的多个方面。
L-精氨酸酶是精氨酸的主要降解酶;它能够将精氨酸转化为鸟氨酸;缺乏该酶与痉挛和运动功能障碍有关。

单位定义

一个酶活性单位是指在pH 9.5、37 °C下,每分钟水解1.0μmol L-精氨酸所需的酶量。
