XLNB — Neurospora crassa

Summary

NCU07225 (XLNB, NcXLNB) on Neurospora crassa chromosome 5 encodes an endo-1,4-beta-xylanase (EC 3.2.1.8) belonging to the glycoside hydrolase family 11 (GH11) and containing a cellulose-binding domain. This enzyme is associated with xylan and D-xylose breakdown, catabolite repression, and is localised extracellularly. The gene is also linked to cellulose binding. Related genes in other species, including Xyn2 and xynB, connect the family to apoplastic effector activity and associations with plant pathogens such as Verticillium dahliae and Fusarium oxysporum.
