'''Glucanases''' (Gase) are enzymes which break down glucans which are part of plant cell wall. Gase hydrolyzes the 1,4-β-glycosidic link in cellulose, lichenin and β-D-glucan. '''Endo-Gase''' breaks internal cellulose bonds<ref>PMID:5354264</ref>. '''Exo-Gase''' cleaves 2 to 4 units from the ends of exposed cellulose polysaccharide chains<ref>PMID:26457517</ref>. '''Xyloglucanase''' (XGase) breaks down the hemicellulose xyloglucan<ref>PMID:9098958</ref>. Gase are classified according to polysaccharide bond which they break. details in [[Molecular Playground/1,3-1,4-beta-D-glucanase]].
