چکیده
negalacturonan (RG) I structure consisting of the diglycosyl repeating unit, -4)-a-D-GaipA-(1.2)-a-LRhap-(1-. The lengths of RG chains were calculated as approximate]y 15, 28, and 100 dig]ycosyl repeats. The RG components linked to each othcr by intcryention of galacturonan (GN) chains, constituting the backbone of SSPS. All arabinose residues, which constitute 21% of total SSPS sugars, were found to be in side chains from RG regiolls, and this was also true for galactose residues; which constitute 50% of total sugars. Of arabinose residues, 94% are present as a-1,3or a-1,5arabinans, and 89% of galactose residues were prese"t

Structural Studies by Stepwise Enzymatic Degradation of the Main of Soybean Soluble Polysaccharides Consisting of Galacturonan and Rhamnogalacturonan JSM
rhamnogalacturonan (RG), which were composed of the diglycosyl repeating "nit, -4)-or-D-GalpA-(1-2)-a-LRhap-(1-. The side chains of B-1,4-galactans, branched with fucose and arabinose residues, were linked to the C-4 side of rhamnose residues in the RG regions. The degree of po]ymerization (dps) of GN, which linked the RG regions together, was estimated to be about 4-10 residues, and some were ...
متن کاملStructural Characterisation of a Polysaccharide from Radix Ranunculus ternati
A water soluble polysaccharide, HB-1, with a molecular weight of 23,930, was isolated from radix Ranunculi ternati. by hot water extraction, ethanol precipitation, deproteination，ultrafiltration and gel-filtration column chromatography. Its sugar composition was determined by GLC as Glc, Ara, and Gal in a molar ration of 16.071: 2.722: 1. And the absolute configuration of Glc was identified as ...

متن کاملCosts and benefits of processivity in enzymatic degradation of recalcitrant polysaccharides.
Many enzymes that hydrolyze insoluble crystalline polysaccharides such as cellulose and chitin guide detached single-polymer chains through long and deep active-site clefts, leading to processive (stepwise) degradation of the polysaccharide. We have studied the links between enzyme efficiency and processivity by analyzing the effects of mutating aromatic residues in the substrate-binding groove...
متن کاملAnalysis of the molecular construction of xylogalacturonan isolated from soluble soybean polysaccharides.
Soluble soybean polysaccharides (SSPS) extracted from soybean cotyledons are acidic polysaccharides, and exhibited a pectin-like structure. After digesting galacturonan with polygalacturonase, two novel galacturonan (GN) fragments, which were directly linked to xylosyl oligosaccharides, were obtained. One consisted of (beta-D-Xyl)7 branched at the C-3 site of 1,4-linked (alpha-D-GalA)4, and the...
