I1S2K3 · XYNA_GIBZE

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

  • Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans.
    EC:3.2.1.8 (UniProtKB | ENZYME | Rhea)

Activity regulation

Inhibited by the proteinaceous endoxylanase inhibitor I from T.aestivum (TAXI-I).
