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 ...
Abstract l-Arabinose is one of the main constituents of cell wall polysaccharides such as pectic rhamnogalacturonan I (RG-I), glucuronoarabinoxylans and other glycoproteins. It is found predominantly in the furanose form rather than in the thermodynamically more stable pyranose form. UDP-L-arabi...
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 ...
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...

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 ...
