    6810   Transport  The Directed Movement of Substances (such As Macromolecules Small Molecules Ions) Into Out of or Within a Cell or Between Cells or Within a Multicellular Organism by Means of Some Agent Such As a Transporter or Pore. 
    15675   Nickel Cation Transport  The Directed Movement of Nickel (ni) Cations Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. 
    50919   Negative Chemotaxis  The Directed Movement of a Motile Cell or Organism Towards a Lower Concentration of a Chemical. 
    55085   Transmembrane Transport  The Process in Which a Solute Is Transported From One Side of a Membrane to the Other. 
    42597   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). 
    43190   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. 
    16151   Nickel Cation Binding  Interacting Selectively and Non Covalently with Nickel (ni) Cations. 
    20037   Heme Binding  Interacting Selectively and Non Covalently with Heme Any Compound of Iron Complexed in a Porphyrin (tetrapyrrole) Ring. 
    46914   Transition Metal Ion Binding  Interacting Selectively and Non Covalently with a Transition Metal Ions; a Transition Metal Is an Element Whose Atom Has an Incomplete D Subshell of Extranuclear Electrons or Which Gives Rise to a Cation or Cations with an Incomplete D Subshell. Transition Metals Often Have More Than One Valency State. Biologically Relevant Transition Metals Include Vanadium Manganese Iron Copper Cobalt Nickel Molybdenum and Silver.
