Cellulase(redirected from Endoglucanase)
Also found in: Dictionary, Medical, Acronyms.
an enzyme of the hydrolase class. Cellulase depolymerizes cellulose polysaccharides (including cellulose itself) and forms glucose or the disaccharide cellobiose. Cellulase is found in germinated grain and in many bacteria and fungi; it is especially active in house fungi that grow on wood. Cellulase is also found in certain animals that feed on wood; these animals include shipworms and Cossidae. Ruminants are able to digest cellulose because symbiotic microorganisms that release cellulase live in the compartments of their stomachs, especially in the rumen.
