High Quality Content by WIKIPEDIA articles! L-(+)-(S)-Canavanine is a non-proteinogenic ?-amino acid found in certain leguminous plants. It is structurally related to the proteinogenic ?-amino acid L-arginine, the sole difference being the replacement of a methylene group in arginine with an oxa group (i.e., an oxygen atom) in canavanine. Canavanine is accumulated primarily in the seeds of the organisms which produce it, where it serves both as a highly deleterious defensive compound against herbivores and a vital source of nitrogen for the growing embryo (see also L-canaline). The mechanism of canavanine's toxicity is that organisms that consume it typically mistakenly incorporate it into their own proteins in place of L-arginine, thereby producing structurally aberrant proteins that may not function properly.
