Metabolite Identification
Common NameCanavanine
DescriptionL-Canavanine, a non-protein amino acid of certain leguminous plants, is related structurally to the protein amino acid, L-arginine. Canavanine is accumulated primarily in the seeds where it serves both as a defensive compound against herbivores and a vital source of nitrogen for the growing embryo. Organisms that consume it can mistakenly incorporate it into their own proteins, in the place of arginine thereby producing structurally aberrant proteins that may not function properly or not at all. Some specialized herbivores tolerate L-canavanine either because they metabolize it efficiently or avoid its incorporation into their own nascent proteins. -- Wikipedia (unverified).

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Produces nitric oxide (NO) which is implicated in vascular smooth muscle relaxation through a cGMP-mediated signal transduction pathway. NO mediates vascular endothelial growth factor (VEGF)-induced angiogenesis in coronary vessels and promotes blood clotting through the activation of platelets. Isoform eNOS13C: Lacks eNOS activity, dominant-negative form that may down-regulate eNOS activity by forming heterodimers with isoform 1.

NOS3
