- β-1,3-glucanase, an enzyme that breaks down β-1,3-glucans such as callose or curdlan
- β-1,6 glucanase, an enzyme that breaks down β-1,6-glucans
- Cellulase, an enzyme that perform the hydrolysis of 1,4-beta-D-glucosidic linkages in cellulose, lichenin and cereal β-D-glucans.
- Xyloglucan-specific endo-beta-1,4-glucanase
- Xyloglucan-specific exo-beta-1,4-glucanase
Glucanases can be produced by Neocallimastigomycota, a phylum of anaerobic fungi found in the digestive tracts of herbivores.
