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. Plays an important role in causing fusarium head blight (FHB) on cereal crops.
Catalytic activity
Activity regulation
Inhibited by the proteinaceous endoxylanase inhibitor I from T.aestivum (TAXI-I).
