Combined administration of ornithine and phenylacetate (OP) is proposed as a novel treatment of hyperammonemia and hepatic encephalopathy. Ornithine is believed to increase ammonia fixation into glutamine in muscle tissue and glutamine is subsequently thought to react with phenylacetate forming

Escherichia coli possesses two acyl ornithine aminotransferases, one catabolic (AstC) and the other anabolic (ArgD), that participate in L-arginine metabolism. Although only 58% identical, the enzymes have been shown to be functionally interchangeable. Here we have purified AstC and have

Reduced production of nitric oxide (NO) is one of the first indications of endothelial dysfunction and precedes overt cardiovascular disease. Increased expression of Arginase has been proposed as a mechanism to account for diminished NO production. Arginases consume l-arginine, the
