CC   -!- FUNCTION: The biological conversion of cellulose to glucose generally
CC       requires three types of hydrolytic enzymes: (1) Endoglucanases which
CC       cut internal beta-1,4-glucosidic bonds; (2) Exocellobiohydrolases that
CC       cut the disaccharide cellobiose from the non-reducing end of the
CC       cellulose polymer chain; (3) Beta-1,4-glucosidases which hydrolyze the
CC       cellobiose and other short cello-oligosaccharides to glucose.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endohydrolysis of (1->4)-beta-D-glucosidic linkages in
CC         cellulose, lichenin and cereal beta-D-glucans.; EC=3.2.1.4;
CC   -!- PATHWAY: Glycan metabolism; cellulose degradation.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 5 (cellulase A) family.
CC       {ECO:0000305}.
