Chain A   (ARAF_ECOLI | P02924)
molecular function
    GO:0048029    monosaccharide binding    Interacting selectively and non-covalently with any monosaccharide. Monosaccharides are the simplest carbohydrates; they are polyhydroxy aldehydes H[CH(OH)]nC(=O)H or polyhydroxy ketones H[CHOH]nC(=O)[CHOH]mH with three or more carbon atoms. They form the constitutional repeating units of oligo- and polysaccharides.
    GO:0015407    monosaccharide-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 + monosaccharide(out) = ADP + phosphate + monosaccharide(in). Ribose, xylose, arabinose, galactose and methylgalactoside are imported.
biological process
    GO:0042882    L-arabinose transport    The directed movement of L-arabinose, the L-enantiomer of arabinose, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    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: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: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).
