L-Arginase is the major degradative enzyme for arginine; converts arginine to ornithine; deficiency is associated with spasticity and motor dysfunction.

Unit Definition

One unit will convert 1.0 μmole of L-arginine to ornithine and urea per min at pH 9.5 at 37 °C.

Physical form

Lyophilized powder containing manganous sulfate and sodium maleate.

Nitric oxide (NO) is a recently discovered mediator produced by mammalian cells. It plays a key role in neurotransmission, control of blood pressure, and cellular defense mechanisms. Nitric oxide synthases (NOSs) catalyze the oxidation of L-arginine to NO and L-citrulline....

Arginase exists in two isoforms, the hepatic (arginase I) and extrahepatic types (arginase II). Arginase I is markedly induced in rat peritoneal macrophages and rat tissues in vivo by bacterial lipopolysaccharide (LPS). In contrast, both arginase I and arginase II...

Arginase is a manganese-dependent enzyme that catalyzes the hydrolysis of L-arginine to L-ornithine and urea. In ureotelic animals arginase is the final enzyme of the urea cycle, but in many species it has a wider role controlling the use of...

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...

Macrophages play a key role in the innate immune response and help to direct the acquired immune response. Early in the innate immune response, they produce reactive oxygen species and pro-inflammatory cytokines and chemokines to drive inflammation and are referred...
