The compound is found in legumes that contain canavanine , from which it is produced by the action of arginase . The most common used source for this amino acid is the jack bean, Canavalia ensiformis . It is grown commercially as a source of the enzyme urease . small L small Canaline is the only naturally occurring amino acid known that has an O alkyl hydroxylamine functionality in the side chain. This amino acid is structurally related to ornithine it is the 5 oxa derivative and is a potent insecticide. Tobacco hornworm larvae fed a diet containing 2.5 mM canaline showed massive developmental aberrations, and most larvae so treated died at the pupal stage. It also exhibits potent neurotoxic effects in the moth. Its toxicity stems primarily from the fact that it readily forms oximes with keto acids and aldehydes, especially the pyridoxal phosphate cofactor of many vitamin B sub 6 sub dependent enzymes. It inhibits ornithine aminotransferase at concentrations as low as 10 nM. small L small Canaline is a substrate for ornithine aminotransferase resulting in the synthesis of small L small ureidohomoserine the corresponding analog of small L small citrulline . In turn, the latter forms small L small canavaninosuccinic acid in a reaction mediated by argininosuccinic acid synthetase . small L small Canavaninosuccinic acid is cleaved to form small L small canavanine by ... more details

Ornithine is abnormally acumulated in the body in ornithine transcarbamylase deficiency . Role in urea cycle small L small Ornithine is one of the products of the action of the enzyme arginase on small L small arginine , creating urea . Therefore, ornithine is a central part of the urea cycle, which allows for the disposal of excess nitrogen . Ornithine is recycled and, in a manner, is a catalyst. First, ammonia is converted into carbamoyl phosphate phosphate CONH sub 2 sub , which creates one half of urea.
