Chain A   (MALE_ECOLI | P0AEX9)
molecular function
    GO:1901982    maltose binding    Interacting selectively and non-covalently with maltose.
    GO:0005363    maltose transmembrane transporter activity    Enables the transfer of maltose from one side of the membrane to the other. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the enzymatic breakdown of glycogen and starch.

    GO:0005215    transporter activity    Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
biological process
    GO:0008643    carbohydrate transport    The directed movement of carbohydrate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Carbohydrates are any of a group of organic compounds based of the general formula Cx(H2O)y.
    GO:0060326    cell chemotaxis    The directed movement of a motile cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).
    GO:0006974    cellular response to DNA damage stimulus    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to its DNA from environmental insults or errors during metabolism.
    GO:0034289    detection of maltose stimulus    The series of events in which a maltose stimulus is received by a cell and converted into a molecular signal.
    GO:0042956    maltodextrin transport    The directed movement of maltodextrin, any polysaccharide of glucose residues in beta-(1,4) linkage, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0015768    maltose transport    The directed movement of maltose into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the catabolism of glycogen and starch.
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
    GO:0043190    ATP-binding cassette (ABC) transporter complex    A complex for the transport of metabolites into and out of the cell, typically comprised of four domains; two membrane-associated domains and two ATP-binding domains at the intracellular face of the membrane, that form a central pore through the plasma membrane. Each of the four core domains may be encoded as a separate polypeptide or the domains can be fused in any one of a number of ways into multidomain polypeptides. In Bacteria and Archaebacteria, ABC transporters also include substrate binding proteins to bind substrate external to the cytoplasm and deliver it to the transporter.
    GO:0055052    ATP-binding cassette (ABC) transporter complex, substrate-binding subunit-containing    A complex for the transport of metabolites into the cell, consisting of 5 subunits: two ATP-binding subunits, two membrane spanning subunits, and one substrate-binding subunit. In organisms with two membranes, the substrate-binding protein moves freely in the periplasmic space and joins the other subunits only when bound with substrate. In organisms with only one membrane the substrate-binding protein is tethered to the cytoplasmic membrane and associated with the other subunits. Transport of the substrate across the membrane is driven by the hydrolysis of ATP.
    GO:1990060    maltose transport complex    Protein complex facilitating ATP-dependent maltose transport through inner cell membrane (periplasm to cytoplasm) in Gram-negative bacteria. In E. coli the system is composed of a periplasmic maltose-binding protein (MBP), two integral membrane proteins, MalF and MalG, and two copies of the cytoplasmic ATP-binding cassette MalK.
    GO:0030288    outer membrane-bounded periplasmic space    The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall.
    GO:0042597    periplasmic space    The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).
