  • Title: Structure of neutral branched xylooligosaccharides produced by xylanase from in situ reduced hardwood xylan.
    Author: Nishimura T, Ishihara M, Ishii T, Kato A.
    Journal: Carbohydr Res; 1998 Mar; 308(1-2):117-22. PubMed ID: 9675358.
    Abstract:
    Two neutral oligosaccharides from in situ reduced hardwood xylan were isolated and completely characterized by methylation analysis and 2D NMR spectroscopy (COSY, HOHAHA, HMQC, HMQC-TOCSY, NOESY, and HMBC techniques). The oligosaccharides are the xylotetrasaccharide, 4-O-methyl-alpha-D-glucopyranosyl-(1-->2)-D-xylotriose and the xylopentasaccharide 4-O-methyl-alpha-D-glucopyranosyl-(1-->2)-D-xylotetraose. From reactivities observed with these compounds, the mode of action of beta-xylanase is described.
