    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. 
    8152   Metabolic Process  The Chemical Reactions and Pathways Including Anabolism and Catabolism by Which Living Organisms Transform Chemical Substances. Metabolic Processes Typically Transform Small Molecules But Also Include Macromolecular Processes Such As DNA Repair and Replication and Protein Synthesis and Degradation. 
    32218   Riboflavin Transport  The Directed Movement of Riboflavin Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. Riboflavin (vitamin B2) Is a Water Soluble B Complex Vitamin Converted in the Cell to Fmn and FAD Cofactors Required For the Function of Flavoproteins. 
    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. 
    166   Nucleotide Binding  Interacting Selectively and Non Covalently with a Nucleotide Any Compound Consisting of a Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Ribose or Deoxyribose. 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    16787   Hydrolase Activity  Catalysis of the Hydrolysis of Various Bonds E.g. C O C N C C Phosphoric Anhydride Bonds Etc. Hydrolase Is the Systematic Name For Any Enzyme of EC Class 3. 
    16887   Atpase Activity  Catalysis of the Reaction: ATP + H2o = Adp + Phosphate + 2 H+. May or May Not Be Coupled to Another Reaction. 
    32217   Riboflavin Transporter Activity  Facilitates the Directed Movement of Riboflavin Into Out of or Within a Cell or Between Cells. Riboflavin (vitamin B2) Is a Water Soluble B Complex Vitamin Converted in the Cell to Fmn and FAD Cofactors Required For the Function of Flavoproteins.

    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.
