RL Biosci. Biotechnol. Biochem. 71:926-934(2007).
CC -!- FUNCTION: Beta-glucanases participate in the metabolism of beta-glucan,
CC the main structural component of the cell wall. It could also function
CC biosynthetically as a transglycosylase (By similarity). {ECO:0000250,
CC ECO:0000269|PubMed:17420593}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Successive hydrolysis of beta-D-glucose units from the non-
CC reducing ends of (1->3)-beta-D-glucans, releasing alpha-glucose.;
CC EC=3.2.1.58;
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000269|PubMed:9758774};
CC -!- SUBUNIT: Monomer. {ECO:0000269|PubMed:9758774}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:9758774}.
CC -!- INDUCTION: The combination of poor nutrition conditions and attachment
CC of mycelia to a hydrophobic solid surface appears to be a major
CC inducing factor. {ECO:0000269|PubMed:17420593}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 5 (cellulase A) family.
CC {ECO:0000305}.
