CC   -!- FUNCTION: Endo-1,4-mannanase, a crucial enzyme for depolymerization of
CC       seed galactomannans and wood galactoglucomannans. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Random hydrolysis of (1->4)-beta-D-mannosidic linkages in
CC         mannans, galactomannans and glucomannans.; EC=3.2.1.78;
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- DOMAIN: Has a modular structure: a carbohydrate-binding module (CBM) at
CC       the N-terminus, a linker rich in serines, and a C-terminal endo-1,4-
CC       mannanase catalytic module. The genes for catalytic modules and CBMs
CC       seem to have evolved separately and have been linked by gene fusion.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 5 (cellulase A) family.
CC       {ECO:0000305}.
