Human arginase 1 (ARG1) is a binuclear manganese metalloenzyme. There are two isozymes of arginase in humans, ARG1 and ARG2. ARG1 is liver-specific and is the primary isozyme involved in the urea cycle. It catalyzes the hydrolysis of L-arginine to form L-ornithine and urea. This reaction is the final step in the urea cycle, which is crucial for the detoxification of ammonia in the body. It is implicated in a variety of human diseases including vascular disease, pulmonary disease, infectious disease, immune cell function and cancer. Arginase deficiency can also result in the accumulation of nitrogen in the form of ammonia, which results in hyperammonemia. Due to its role in various physiological processes, ARG1 is a potential target for treating conditions like cardiovascular diseases, erectile dysfunction, and immune disorders.
