Chain A,B,C,D   (MALK_ECOLI | P68187)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0016887    ATPase activity    Catalysis of the reaction: ATP + H2O = ADP + phosphate + 2 H+. May or may not be coupled to another reaction.
    GO:0033613    activating transcription factor binding    Interacting selectively and non-covalently with an activating transcription factor, any protein whose activity is required to initiate or upregulate transcription.
    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:0016820    hydrolase activity, acting on acid anhydrides, catalyzing transmembrane movement of substances    Catalysis of the hydrolysis of an acid anhydride to directly drive the transport of a substance across a membrane.
    GO:0015609    maltooligosaccharide-importing ATPase activity    Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O + maltooligosaccharide(out) -> ADP + phosphate + maltooligosaccharide(in).
    GO:0015423    maltose-transporting ATPase activity    Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O + maltose(out) = ADP + phosphate + maltose(in).
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    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: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:0055085    transmembrane transport    The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
    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:0031234    extrinsic component of cytoplasmic side of plasma membrane    The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to its cytoplasmic surface, but not integrated into the hydrophobic region.
    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:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
