Metabolite Identification
Common NameUDP-D-apiose
DescriptionD-Apiose is a plant-specific branched-chain monosaccharide found in rhamnogalacturonan II (RG-II), apiogalacturonan, and several apioglycosides. Within RG-II, D-apiose serves as the binding site for borate, which leads to the formation of cross-links within the wall. Biochemical studies in duckweed and parsley have established that uridine 5'-diphospho-D-apiose (UDP-D-apiose) is formed from UDP-D-glucuronate by decarboxylation and re-arrangement of the carbon skeleton, leading to ring contraction and branch formation. The enzyme catalyzing this reaction also forms UDP-D-xylose by decarboxylation of UDP-D-glucuronate, and has therefore been named UDP-D-apiose/UDP-D-xylose synthase (PMID: 12969423 ).
