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。
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。
General description
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。
Other Notes
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。

Urea producing bimetallic arginases are essential for the synthesis of polyamine, DNA, and RNA. Despite conservation of the signature motifs in all arginases, a nonconserved ¹⁵³ESEEKAWQKLCSL¹⁶⁵ motif is found in the Helicobacter pylori enzyme, whose role is yet unknown. Using
