Names and origin

Protein names	Recommended name:     Endoglucanase     EC=3.2.1.4 Alternative name(s):     Endo-1,4-beta-glucanase     Alkaline cellulase
Organism	Bacillus sp. (strain 1139)
Taxonomic identifier	1411 [NCBI]
Taxonomic lineage	Bacteria › Firmicutes › Bacillales › Bacillaceae › Bacillus

Protein attributes

Sequence length	800 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Catalytic activity	Endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.
Miscellaneous	Alkalophilic Bacillus sp strain 1139 is not a true cellulolytic micro-organism because the enzyme is unable to hydrolyze native cellulose.
Sequence similarities	Belongs to the glycosyl hydrolase 5 (cellulase A) family.
biophysicochemical properties	pH dependence: Optimum pH is 9.0.
