| Enzyme Function | FUNCTION: Endo-1,4-beta-xylanase involved in the hydrolysis of xylan, a major structural heterogeneous polysaccharide found in plant biomass representing the second most abundant polysaccharide in the biosphere, after cellulose. Hydrolyzes both unsubstituted (oat spelts) and highly substituted (rye and wheat) forms of arabinoxylanslans. |
