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[1].
- Exo-Gase cleaves 2 to 4 units from the ends of exposed cellulose polysaccharide chains[2]. *Xyloglucanase (XGase) breaks down the hemicellulose xyloglucan[3].
- alpha-1,3-glucanase hydrolyzes alpha-1,3-glucan [4].
- beta-1,3-glucanase enhances fungal resistance in plants[5].
Gase are classified according to polysaccharide bond which they break. For details see
