Chain A,B,C,D,E,F   (BFRA_THEMA | O33833)
molecular function
    GO:0004564    beta-fructofuranosidase activity    Catalysis of the reaction: a fructofuranosylated fructofuranosyl acceptor + H2O = a non fructofuranosylated fructofuranosyl acceptor + a beta-D-fructofuranoside.
    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:0004575    sucrose alpha-glucosidase activity    Catalysis of the reaction: sucrose + H2O = alpha-D-glucose + beta-D-fructose.
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:0005987    sucrose catabolic process    The chemical reactions and pathways resulting in the breakdown of sucrose, the disaccharide fructofuranosyl-glucopyranoside.
