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

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
