Biosynthesis of proteoglycans and glycosaminoglycans in the presence of p-nitrophenyl-xyloside was studied using a primary rat ovarian granulosa cell culture system. Addition of p-nitrophenyl-xyloside into cell culture medium caused about a 700% increase of [³⁵S]sulfate incorporation (ED50 at 0.03 mM)

A beta-xylosidase from Bacillus stearothermophilus T-6 was cloned, overexpressed in Escherichia coli and purified to homogeneity. Based on sequence alignment, the enzyme belongs to family 39 glycoside hydrolases, which itself forms part of the wider GH-A clan. The conserved Glu160

Di-O-acetates and mono-O-acetates of 4-nitrophenyl beta-D-xylopyranoside were prepared by use of lipase PS-30. Polarity of organic solvents and reaction time affected the regioselectivity of the di-O-acetylation as well as the yields of monoacetates. The kinetics of acetyl groups migration in

Positional specificity of NodB-like domain of a multidomain xylanase U from Clostridium thermocellum (CtAxe) was investigated. Of three monoacetates of 4-nitrophenyl beta-d-xylopyranoside the acetylxylan esterase domain showed a clear preference for the 2-acetate. Moreover, the enzyme was significantly activated by

Chondroitin/dermatan sulphate (CS/DS) sulphation motifs on cell and extracellular matrix proteoglycans (PGs) within stem/progenitor cell niches are involved in modulating cell phenotype during the development of many musculoskeletal connective tissues. Here, we investigate the importance of CS/DS chains and their
