Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (MODA_ECOLI | P37329)
molecular function
    GO:0015412    ATPase-coupled molybdate transmembrane transporter 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 + molybdate(out) = ADP + phosphate + molybdate(in).
biological process
    GO:0015689    molybdate ion transport    The directed movement of molybdate (MoO4 2-) ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Molybdate is the bivalent anion derived from molybdic acid.
    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).
