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 {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose
CC and cellotetraose, releasing cellobiose from the non-reducing ends of
CC the chains.; EC=3.2.1.91;
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 7 (cellulase C) family.
CC {ECO:0000305}.
