    Chain A
    GO ID   Ontology GO Term Definition
    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. 
    6974   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. 
    8643   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. 
    15768   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. 
    34289   Detection of Maltose Stimulus  The Series of Events in Which a Maltose Stimulus Is Received by a Cell and Converted Into a Molecular Signal. 
    42956   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. 
    60326   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). 
    30288   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 Cell Wall. 
    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. 
    55052   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. 
    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. 
    5215   Transporter Activity  Enables the Directed Movement of Substances (such As Macromolecules Small Molecules Ions) Into Out of or Within a Cell or Between Cells. 
    5363   Maltose Transmembrane Transporter Activity  Catalysis of 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. 
    5515   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). 
    1901982   Maltose Binding  Interacting Selectively and Non Covalently with Maltose.
