Arginase I (human) (rec.) (highly active)

Protein function: Key element of the urea cycle converting L-arginine to urea and L-ornithine, which is further metabolized into metabolites proline and polyamides that drive collagen synthesis and bioenergetic pathways critical for cell proliferation, respectively, the urea cycle takes place primarily in the liver and, to a lesser extent, in the kidneys.
