D-Apiose, a plant-specific branched-chain monosaccharide found in rhamnogalacturonan II (RG-II), apiogalacturonan, and several apioglycosides, serves as a borate binding site for crosslinking of galacturonans within plant cell walls.

D-apiose serves as the binding site for borate cross-linking of rhamnogalacturonan II (RG-II) in the plant cell wall, and biosynthesis of D-apiose involves UDP-D-apiose/UDP-D-xylose synthase catalyzing the conversion of UDP-D-glucuronate to a mixture of UDP-D-apiose and UDP-D-xylose. In this study

Rhamnogalacturonan II (RG-II) is a structurally complex pectic mega-oligosaccharide that is released enzymatically from the primary cell wall of higher plants. It contains roughly 30 monosaccharide units (MW approximately 5 kDa) including very unusual residues such as Kdo, Dha, aceric

Plants possess a sophisticated sugar biosynthetic machinery comprising families of nucleotide sugar interconversion enzymes. Literature published in the past two years has made a major contribution to our knowledge of the enzymes and genes involved in the interconversion of nucleotide
Beta-rhamnosylation of methyl 2-C-hydroxymethyl-2,3-O-isopropylidene-beta-D-erythrofuranoside and methyl 2,3-O-isopropylidene-beta-D-ribofuranoside was achieved using 4-O-acetyl-2,3-O-carbonyl-alpha-L-rhamnopyranosyl bromide and Ag2O as a promoter. Deprotected disaccharides beta-L-Rhap-(1-->3')-beta-D-Apif-OMe and beta-L-Rhap-(1-->3')-beta-D-Ribf-OMe were compared to their alpha-rhamnosyl isomers which were prepared using conventional Helferich glycosylation.
