- noun An enzyme found primarily in the liver that catalyzes the hydrolysis of arginine to form urea and ornithine.
from The Century Dictionary.
- noun A ferment which causes the decomposition of arginin into ornithin and urea. It has been found in the liver, the thymus, lymph glands, the mucosa of the small intestine, etc.

Aminoacidopathies (maple syrup urine disease; homocystinuria; cobalamin deficiencies; tyrosinemia; urea cycle defects (ornithine transcarbamylase, carbamyl phosphate synthase, citrullinemia, argininosuccinic aciduria, arginase deficiencies) and non-ketotic hyperglycinemia)
D. Dakin he investigated arginase, the ferment which hydrolyses arginine into urea and ornithine, and later he discovered agmatine in herring roe and devised a method for preparing it.
In the periphery, the NO production decrease may reflect an arginase-mediated synthesis of polyamines necessary to trypanosome growth.
Elevated levels of the enzyme arginase contribute to vascular eye damage and Medical College of Geor ...
To test whether the predominance of the arginase expression over that of the iNOS endowed M2 MØ with reparative capabilities, vascular smooth muscle cells (VSMCs) were cultured with MØ-conditioned medium.

B: Primary aortic vascular smooth muscle cells (VSMCs) from C57Bl/6 mice were cultured for 48 hours in the presence of media conditioned by C57Bl/6 M1 or M2 MØ which were polarized in the presence of the PPARγ agonist pioglitazone (Pio), the PPARγ antagonist GW9662 (GW), or the arginase inhibitor Nor-NOHA.
In the present study, we used Arg I and Arg II as surrogate markers of M1 and M2 MØ since these two isoforms of arginase were distinctly upregulated in bone marrow-derived M1 and M2 MØ polarized in vitro.
