Xylotetraose Usage And Synthesis

Uses

Xylotetrose is a xylose oligomer that is of interest to many fields of study and is an intermediate reaction product of the hydrolysis of hemicelluloses.

Definition

ChEBI: A tetrasaccharide comprised of four D-xylose residues connected by β(1→4) linkages.

Reactions

A novel xylanase (xylanase IV) which produces xylotetraose as the only low-molecular-weight oligosaccharide from oat spelt xylan was isolated from the culture medium of Aeromonas caviae ME-1. By sodium dodecyl sulfate-polyacrylamide gel electrophoresis, the xylanase IV molecular weight was 41,000. Xylanase IV catalyzed the hydrolysis of oat spelt xylan, producing exclusively xylotetraose. The acid hydrolysate of the product gave d-xylose. The enzyme did not hydrolyze either p-nitrophenyl-(beta)-d-xyloside, small oligosaccharides (xylobiose and xylotetraose), or polysaccharides, such as starch, cellulose, carboxymethyl cellulose, laminarin, and (beta)-1,3-xylan.
