| GO term | GO name | GO namespace | GO def |
| GO:0008152 | metabolic process | biological_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. [GOC:go_curators, ISBN:0198547684] |
| GO:0009987 | cellular process | biological_process | Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. [GOC:go_curators, GOC:isa_complete] |
| GO:0016829 | lyase activity | molecular_function | 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. [ISBN:0198547684] |
| GO:0110165 | cellular anatomical entity | cellular_component | A part of a cellular organism that is either an immaterial entity or a material entity with granularity above the level of a protein complex but below that of an anatomical system. Or, a substance produced by a cellular organism with granularity above the level of a protein complex. [GOC:kmv] |
| GO:0031982 | vesicle | cellular_component | Any small, fluid-filled, spherical organelle enclosed by membrane. [GOC:mah, GOC:pz, GOC:vesicles] |
| GO:0044237 | cellular metabolic process | biological_process | The chemical reactions and pathways by which individual cells transform chemical substances. [GOC:go_curators] |
| GO:0005576 | extracellular region | cellular_component | The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. [GOC:go_curators] |
| GO:0009593 | detection of chemical stimulus | biological_process | The series of events in which a chemical stimulus is received by a cell and converted into a molecular signal. [GOC:jl] |
| GO:0044281 | small molecule metabolic process | biological_process | The chemical reactions and pathways involving small molecules, any low molecular weight, monomeric, non-encoded molecule. [GOC:curators, GOC:pde, GOC:vw] |
| GO:0043226 | organelle | cellular_component | Organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, and prokaryotic structures such as anammoxosomes and pirellulosomes. Excludes the plasma membrane. [GOC:go_curators] |
| GO:0043227 | membrane-bounded organelle | cellular_component | Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. [GOC:go_curators] |
| GO:0051606 | detection of stimulus | biological_process | The series of events in which a stimulus is received by a cell or organism and converted into a molecular signal. [GOC:add, GOC:ai, GOC:dph, GOC:mah] |
| GO:0008270 | zinc ion binding | molecular_function | Binding to a zinc ion (Zn). [GOC:ai] |
| GO:0016835 | carbon-oxygen lyase activity | molecular_function | Catalysis of the breakage of a carbon-oxygen bond. [EC:4.2.-.-] |
| GO:0003824 | catalytic activity | molecular_function | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. [GOC:vw, ISBN:0198506732] |
| GO:0050896 | response to stimulus | biological_process | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism. [GOC:ai, GOC:bf] |
| GO:0005615 | extracellular space | cellular_component | That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid. [ISBN:0198547684] |
| GO:0005829 | cytosol | cellular_component | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl] |
| GO:0016836 | hydro-lyase activity | molecular_function | Catalysis of the cleavage of a carbon-oxygen bond by elimination of water. [EC:4.2.1.-] |
