GO term | GO name | GO namespace | GO def |
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:1901360 | organic cyclic compound metabolic process | biological_process | The chemical reactions and pathways involving organic cyclic compound. [GOC:TermGenie] |
GO:1901564 | organonitrogen compound metabolic process | biological_process | The chemical reactions and pathways involving organonitrogen compound. [GOC:pr, GOC:TermGenie] |
GO:0006725 | cellular aromatic compound metabolic process | biological_process | The chemical reactions and pathways involving aromatic compounds, any organic compound characterized by one or more planar rings, each of which contains conjugated double bonds and delocalized pi electrons, as carried out by individual cells. [GOC:ai, ISBN:0198506732] |
GO:0008233 | peptidase activity | molecular_function | Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid. [GOC:jl, ISBN:0815332181] |
GO:0046483 | heterocycle metabolic process | biological_process | The chemical reactions and pathways involving heterocyclic compounds, those with a cyclic molecular structure and at least two different atoms in the ring (or rings). [ISBN:0198506732] |
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:0004252 | serine-type endopeptidase activity | molecular_function | Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine). [GOC:mah, https://www.ebi.ac.uk/merops/about/glossary.shtml#CATTYPE] |
GO:0071704 | organic substance metabolic process | biological_process | The chemical reactions and pathways involving an organic substance, any molecular entity containing carbon. [GOC:mah] |
GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
GO:0006874 | cellular calcium ion homeostasis | biological_process | Any process involved in the maintenance of an internal steady state of calcium ions at the level of a cell. [GOC:ceb, GOC:mah] |
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:0033013 | tetrapyrrole metabolic process | biological_process | The chemical reactions and pathways involving tetrapyrroles, natural pigments containing four pyrrole rings joined by one-carbon units linking position 2 of one pyrrole ring to position 5 of the next. [GOC:mah] |
GO:0006807 | nitrogen compound metabolic process | biological_process | The chemical reactions and pathways involving organic or inorganic compounds that contain nitrogen. [GOC:jl, ISBN:0198506732] |
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:0044237 | cellular metabolic process | biological_process | The chemical reactions and pathways by which individual cells transform chemical substances. [GOC:go_curators] |
GO:0006508 | proteolysis | biological_process | The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. [GOC:bf, GOC:mah] |
