Chain A   (SACB_BACSU | P05655)
molecular function
    GO:0050053    levansucrase activity    Catalysis of the reaction: sucrose + 2,6-beta-D-fructosyl(n) = glucose + 2,6-beta-D-fructosyl(n+1).
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
    GO:0016757    transferase activity, transferring glycosyl groups    Catalysis of the transfer of a glycosyl group from one compound (donor) to another (acceptor).
biological process
    GO:0009758    carbohydrate utilization    A series of processes that forms an integrated mechanism by which a cell or an organism detects the depletion of primary carbohydrate sources,usually glucose, and then activates genes to scavenge the last traces of the primary carbohydrate source and to transport and metabolize alternate carbohydrate sources. The utilization process begins when the cell or organism detects carbohydrate levels, includes the activation of genes whose products detect, transport or metabolize carbohydrates, and ends when the carbohydrate is incorporated into the cell or organism's metabolism.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
