    Chain A
    GO ID   Ontology GO Term Definition
    51453   Regulation of Intracellular Ph  Any Process That Modulates the Internal Ph of a Cell Measured by the Concentration of the Hydrogen Ion. 
    2001150   Positive Regulation of Dipeptide Transmembrane Transport  Any Process That Activates or Increases the Frequency Rate or Extent of Dipeptide Transmembrane Transport. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5886   Plasma Membrane  The Membrane Surrounding a Cell That Separates the Cell From Its External Environment. It Consists of a Phospholipid Bilayer and Associated Proteins. 
    16020   Membrane  Double Layer of Lipid Molecules That Encloses All Cells and in Eukaryotes Many Organelles; May Be a Single or Double Lipid Bilayer; Also Includes Associated Proteins. 
    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). 
    16829   Lyase Activity  Catalysis of the Cleavage of C C C O C N and Other Bonds by Other Means Than by Hydrolysis or Oxidation or Conversely Adding a Group to a Double Bond. They Differ From Other Enzymes in That Two Substrates Are Involved in One Reaction Direction But Only One in the Other Direction. When Acting On the Single Substrate a Molecule Is Eliminated and This Generates Either a New Double Bond or a New Ring. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
