    GO ID   Ontology GO Term Definition
    422   Mitophagy  The Autophagic Process in Which Mitochondria Are Delivered to the Vacuole and Degraded in Response to Changing Cellular Conditions. 
    6464   Cellular Protein Modification Process  The Covalent Alteration of One or More Amino Acids Occurring in Proteins Peptides and Nascent Polypeptides (co Translational Post Translational Modifications) Occurring At the Level of an Individual Cell. Includes the Modification of Charged Trnas That Are Destined to Occur in a Protein (pre Translation Modification). 
    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. 
    6914   Autophagy  The Process in Which Cells Digest Parts of Their Own Cytoplasm; Allows For Both Recycling of Macromolecular Constituents Under Conditions of Cellular Stress and Remodeling the Intracellular Structure For Cell Differentiation. 
    15031   Protein Transport  The Directed Movement of Proteins Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. 
    16236   Macroautophagy  The Major Inducible Pathway For the General Turnover of Cytoplasmic Constituents in Eukaryotic Cells It Is Also Responsible For the Degradation of Active Cytoplasmic Enzymes and Organelles During Nutrient Starvation. Macroautophagy Involves the Formation of Double Membrane Bounded Autophagosomes Which Enclose the Cytoplasmic Constituent Targeted For Degradation in a Membrane Bounded Structure. Autophagosomes Then Fuse with a Lysosome (or Vacuole) Releasing Single Membrane Bounded Autophagic Bodies That Are Then Degraded Within the Lysosome (or Vacuole). Though Once Thought to Be a Purely Non Selective Process It Appears That Some Types of Macroautophagy E.g. Macropexophagy Macromitophagy May Involve Selective Targeting of the Targets to Be Degraded. 
    32258   Cvt Pathway  A Constitutive Biosynthetic Process That Occurs Under Nutrient Rich Conditions in Which Two Resident Vacuolar Hydrolases Aminopeptidase I and Alpha Mannosidase Are Sequestered Into Vesicles; These Vesicles Are Transported to and Then Fuse with the Vacuole. This Pathway Is Mostly Observed in Yeast. 
    34727   Piecemeal Microautophagy of Nucleus  Degradation of a Cell Nucleus by Microautophagy. 
    44805   Late Nucleophagy  A Type of Nucleophagy Distinct From Piecemeal Microautophagy of the Nucleus (pnm) Where the Nuclear Material Is Delivered to the Vacuole/lysosome For Breakdown and Recycling Later Than Observed For Pnm. 
    5575   Cellular_component  The Part of a Cell or Its Extracellular Environment in Which a Gene Product Is Located. a Gene Product May Be Located in One or More Parts of a Cell and Its Location May Be As Specific As a Particular Macromolecular Complex That Is a Stable Persistent Association of Macromolecules That Function Together. 
    16020   Membrane  A Lipid Bilayer Along with All the Proteins and Protein Complexes Embedded in It an Attached to It. 
    34045   Pre Autophagosomal Structure Membrane  A Cellular Membrane Associated with the Pre Autophagosomal Structure. 
    16874   Ligase Activity  Catalysis of the Joining of Two Substances or Two Groups Within a Single Molecule with the Concomitant Hydrolysis of the Diphosphate Bond in ATP or a Similar Triphosphate. 
    19777   Atg12 Transferase Activity  Catalysis of the Transfer of Atg12 From One Protein to Another Via the Reaction X Atg12 + Y > Y Atg12 + X Where Both X Atg12 and Y Atg12 Are Covalent Linkages.
