Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (A3DCH2_CLOTH | A3DCH2)
molecular function
    GO:0030246    carbohydrate binding    Interacting selectively and non-covalently with any carbohydrate, which includes monosaccharides, oligosaccharides and polysaccharides as well as substances derived from monosaccharides by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom. Cyclitols are generally not regarded as carbohydrates.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0008810    cellulase activity    Catalysis of the endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.
    GO:0030248    cellulose binding    Interacting selectively and non-covalently with cellulose.
    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:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
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: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.
