csn — Aspergillus fumigatus

Summary

AFU8G00930 (csn) on chromosome 8 of Aspergillus fumigatus encodes a protein with a fungal chitosanase domain and chitosanase activity (EC 3.2.1.132). The gene is associated with digestion, polysaccharide breakdown, fermentation, and secretion, and its product is localised to the extracellular space. Studies of related genes in other species link the family to chitosan degradation, though this specific role is not yet established in A. fumigatus.
