Chain A,B   (MANA_CELJU | P49424)
molecular function
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0016798    hydrolase activity, acting on glycosyl bonds    Catalysis of the hydrolysis of any glycosyl bond.
    GO:0004553    hydrolase activity, hydrolyzing O-glycosyl compounds    Catalysis of the hydrolysis of any O-glycosyl bond.
    GO:0016985    mannan endo-1,4-beta-mannosidase activity    Catalysis of the random hydrolysis of (1->4)-beta-D-mannosidic linkages in mannans, galactomannans, glucomannans, and galactoglucomannans.
biological process
    GO:0005975    carbohydrate metabolic process    The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule.
    GO:0051069    galactomannan metabolic process    The chemical reactions and pathways involving galactomannan, a polysaccharide composed of D-galactose and D-mannose. The mannose units form the backbone structure (a linear main chain) with the D-galactose as single side units.
    GO:0010391    glucomannan metabolic process    The chemical reactions and pathways involving glucomannan, a polysaccharide composed of D-glucose and D-mannose. The mannose units form the backbone structure (a linear main chain) with the D-glucose as single side-units.
    GO:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
    GO:0000272    polysaccharide catabolic process    The chemical reactions and pathways resulting in the breakdown of a polysaccharide, a polymer of many (typically more than 10) monosaccharide residues linked glycosidically.
    GO:0006080    substituted mannan metabolic process    The chemical reactions and pathways involving a mannan backbone composed of D-mannose unites, substituted with D-glucose and/or D-galactose units.
