action pattern of type I occurs in the hydrolysis by enzyme form EF-1, EF-2 and EF-5: beta-1,3-xylobiose, beta-1,3-xylotriose, beta-1,3-xylotetraose and an unknown disaccharide are liberated. The action pattern of type II occurs during hydrolysis by enzyme form EF-4 and EF-6. In the initial stage the enzyme produces mainly beta-1,2-xylobiose, beta-1,3-xylotriose and beta-1,3-xylotetraose. As hydrolysis proceeds an isomeric xylotriose is detectable as well as xylose, beta-1,3-xylobiose, beta-1,3-xylotriose and beta-1,3-xylotetraose

XYL4, an endo-type enzyme, contains two putative carbohydrate-binding modules, CBMs, belonging to family 31 in the C-terminal region. Repeating CBMs bind specifically to insoluble beta-1,3-xylan, but not to beta-1,4-xylan, Avicel, beta-1,4-mannan, curdlan, chitin or soluble glycol-beta-1,3-xylan, through hydrophobic interaction.
