The familial disease of hereditary multiple exostoses is characterized by abnormal skeletal deformities requiring extensive surgical procedures. In hereditary multiple exostoses patients there is a shortage in the pericellular glycosaminoglycan (GAG) of heparan sulfate (HS), related to defective activity of

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

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
