UDP-L-arabinofuranose (UDP-Araf), rather than UDP-L-arabinopyranose (UDP-Arap), is a sugar donor for the biosynthesis of arabinofuranosyl (Araf) residues. UDP-arabinopyranose mutases (UAMs) have been shown to interconvert UDP-Araf and UDP-Arap and are involved in the biosynthesis of ...
The pentoses consist ofribose,deoxyribose,arabinose,xylose,lyxose, anderythrupentulose(Mathews and Van Holde 1990; Carey 1992). The sugar 2-deoxy-D-ribose is a component of the DNA molecule. Thehexoseswhich are of common occurrence in most plants areglucose,fructose,mannose, andgalactose. They ...

The yeast grew in xylose, arabinose and glucose at the same rate at an initial medium pH of 5.5. At pH 4.5, the yeast grew more slowly in arabinose. There was no sugar exhaustion within 60 h. At higher xylose concentrations with a higher initial cell concentration, sugar was exhausted ...
japonica is a heteropolysaccharide, mainly made of fucose, galactose, and sulfate, with smaller amounts of mannoses, glucuronic acid, glucose, rhamnose, arabinose and xylose (Zhang et al., 2008). Laminaria digitata specimens are collected extensively for the industrial production of alginate, used...
These data differ from a recent study using bioreactor cultures, where D-mannose consumption did not start until D-glucose was nearly depleted and D-xylose, L-arabinose and D-galacturonic acid were consumed simultaneously11. As sugar transport has been shown to be pH-dependent12,13, this ...

Xylosidase is essentially specific for xylose residues; arabinofurano- sidase will release both arabinose and xylose residues22–25. We determined the profile of AX-degrading enzymes in the endosperm during germination and early seedling growth, using 4-nitrophenyl derivatives of substrates of these ...

The synthesis of customized glycoconjugates constitutes a major goal for biocatalysis. To this end, engineered glycosidases have received great attention and, among them, thioglycoligases have proved useful to connect carbohydrates to non-sugar acceptors. However, hitherto the scope of these biocatalysts...
