Abstract Endo-beta-1,4-xylanases are key enzymes in the degradation of arabinoxylans, the main non-starch polysaccharides from grain cell walls. Due to the heterogeneity of arabinoxylans, xylanases with different characteristics are required in industrial applications but the choice of the enzyme is still largely empirical. Although the classification into glycoside hydrolase families greatly helped to derive mechanistic information on the catalytic and substrate specificity of xylanases, other factors e.g. their sensitivity to endogenous inhibitors, the presence of carbohydrate-binding module(s) and their degree of selectivity towards soluble versus insoluble substrate may play a role in determining the functionality of these enzymes in the degradation of arabinoxylans.
