L-Canaline
L-canaline, also known as L-2-amino-4-(aminooxy)butyric acid, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. L-canaline is soluble (in water) and a moderately acidic compound (based on its pKa). L-canaline can be found in a number of food items such as mulberry, rape, grape, and black chokeberry, which makes L-canaline a potential biomarker for the consumption of these food products. L-canaline is a substrate for ornithine aminotransferase resulting in the synthesis of L-ureidohomoserine (the corresponding analog of L-citrulline). In turn, the latter forms L-canavaninosuccinic acid in a reaction mediated by argininosuccinic acid synthetase. L-Canavaninosuccinic acid is cleaved to form L-canavanine by argininosuccinic acid synthetase. By these sequential reactions, the canaline-urea cycle (analogous to the ornithine-urea cycle) is formed. Every time a canavanine molecule runs through the canaline-urea cycle, the two terminal nitrogen atoms are released as urea. Urea is an important by-product of this reaction sequence because it makes ammonicial ammonia (urease-mediated) that is available to support intermediary nitrogen metabolism. L-canaline can by reductively cleaved to L-homoserine, a non-protein amino acid of great importance in the formation of a host of essential amino acids. In this way, the third nitrogen atom of canavanine enters into the reactions of nitrogen metabolism of the plant. As homoserine, its carbon skeleton also finds an important use . L-canaline is a non-proteinogenic L-alpha-amino acid that is L-homoserine in which the hydroxy group at position 4 is substituted by an aminooxy group. It has been isolated from legumes and plays an essential role in lugume chemical defense against insects. It has a role as a plant metabolite, an antineoplastic agent, an antimetabolite and a phytogenic insecticide. It is functionally related to a L-homoserine. It is a tautomer of a L-canaline zwitterion. Canavanine reacts with water to produce L-canaline and urea. The reaction is catalyzed by arginase. L-canaline reacts with carbamoyl-phosphate to produce O-ureidohomoserine and phosphate. The reaction is catalyzed by ornithine carbamoyltransferase. A non-proteinogenic L-alpha-amino acid that is L-homoserine in which the hydroxy group at position 4 is substituted by an aminooxy group. It has been isolated from legumes and plays an essential role in lugume chemical defense against insects.
