Synthesis of beta-D-glucose oligosaccharides from Phytophthora parasitica.
The glucohexaose, beta-D-Glcp-(1-->3)-[beta-D-Glcp-(1-->3)-beta-D-Glcp-(1-->3)-beta-D-Glcp-(1-->6)]-beta-D-Glcp-(1-->3)-D-Glcp, was synthesized as its allyl glycoside via 3+3 strategy. The trisaccharide donor, 2,3,4,6-tetra-O-benzoyl-beta-D-glucopyranosyl-(1-->3)-2,4,6-tri-O-acetyl-beta-D-glucopyranosyl-(1-->3)-2,4,6-tri-O-acetyl-alpha-D-glucopyranosyl trichloroacetimidate (11), was obtained by...
متن کاملSynthesis of phenylazonaphtol-β-D-O-glycosides, evaluation as substrates for beta-glycosidase activity and molecular studies
BACKGROUND Phenylazonaphtol-β-D-O-glycosides are alternative substrates for the detection of enzymatic activity of β-glycosidases which are involved in various important processes. These azoic compounds are currently exploited as prodrugs for colonic disease due the presence of β-glycosidase activity in the gut flora and therefore allowing the release of the drug at the specific site. RESULTS...
متن کاملIsolation and characterization of a beta-primeverosidase-like endo-manner beta-glycosidase from Aspergillus fumigatus AP-20.
A novel beta-glycosidase-producing microorganism was isolated from soil and identified as Aspergillus fumigatus AP-20 based on its taxonomical characteristics. The enzyme was found to be an extracellular protein in the culture of the isolated fungus and was purified 88-fold by fractionation with ammonium sulfate followed by successive column chromatographies on phenyl-Sepharose HP and Mono P HR...
متن کاملStructural basis for thermostability of beta-glycosidase from the thermophilic eubacterium Thermus nonproteolyticus HG102.
The three-dimensional structure of a thermostable beta-glycosidase (Gly(Tn)) from the thermophilic eubacterium Thermus nonproteolyticus HG102 was determined at a resolution of 2.4 A. The core of the structure adopts the (betaalpha)(8) barrel fold. The sequence alignments and the positions of the two Glu residues in the active center indicate that Gly(Tn) belongs to the glycosyl hydrolases of re...
