Structure of Aldouronic Acids Liberated from Kenaf Xylan by Endozsylanase from Streptomyces sp.

摘要：

Introduction In a previous paper, we reported the chemical structure of xylan isolated from kenaf (Hibiscus cannabinus). The main chain of xylan consisted of (1-4)-linked β-D-Xylp residues, some of which carried α-(1-2)-Iinked 4-O-Me-GIcAp and GIcAp residues as single side chains. Furthermore, 4-O-(α-GalAp)-D-Xylp was isolated from the partial hydrolysates of the xylan. This paper reports the structure of aldouronic acids liberated from the xylan from kenaf core by the partially purified endo-acting xylanases from Streptomyces sp. SK 519. The structures of such oligosaccharides can give detailed information on the structure of the polysaccharides as well as about the substrate specificity of the applied enzymes.
