The data in Table I show that the enzyme acts with highest velocity on maltotetraose and oligosaccharides of higher molecular weight. The rate of action on maltotriose is one-half of the rate for the tetrasaccharide, and on maltose the rate is only one-tenth of the rate for the tetrasaccharide. Oligosaccharides in which the glucose units are joined by linkages other than a-1,4 are hydrolyzed at much slower rates than the 1,4...

The D-xylanases of rumen microbial origin are all of the endo type, and degrade D-xylan, arabinoxylan, hemicellulose B, and xylo-oligosaccharides of d.p. 2=3, mainly to X2 and D-xylose X2 remains unattacked. The D-xylanases were found38,42 to have a higher affinity for linear D-xylans than for the branched hemicelluloses, namely, arabinoxylan and a branched B fraction from Trifolium pratense (red clover). The presence of L-arabinose, D-galactose, and uronic acid substituents on the D-xylan backbone thus appears to inhibit the action of these D-xylanases. The D-xylan was not effectively hydrolyzed until the side-group substituents had mostly been removed, for example, by arabinofuranosidase action on arabinoxylan.44...
