The tobacco budworm Heliothis virescens can metabolize a toxic analogue of this chemical called canavanine found in leguminous plants.  
The tobacco budworm Heliothis virescens can metabolize a toxic analogue of this chemical called canavanine found in leguminous plants.  This chemical is the substrate of a family of synthases that require electron flow between NADPH, FAD, FNM, BH-four, heme, and finally O-two. A competing enzyme containing manganese cleaves a one-carbon molecule from this chemical in the final step of a cycle that begins by joining carbamoyl phosphate to ornithine. Those enzymes produce nitric oxide and urea respectively, the second of which occurs in a cycle that sees this amino acid formed from citrulline. This amino acid's side chain contains a carbon atom bonded to three nitrogen atoms with a floating positive change.  FTP, name this basic amino acid with a guandinium side chain.
