molecular function |
| GO:0004180 | | carboxypeptidase activity | | Catalysis of the hydrolysis of the terminal or penultimate peptide bond at the C-terminal end of a peptide or polypeptide. |
| GO:0016787 | | 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. |
| GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| GO:0008237 | | metallopeptidase activity | | Catalysis of the hydrolysis of peptide bonds by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions. |
| GO:0008233 | | peptidase activity | | 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. |
| GO:0008241 | | peptidyl-dipeptidase activity | | Catalysis of the release of C-terminal dipeptides from a polypeptide chain. |
| GO:0005515 | | 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). |
| GO:0008270 | | zinc ion binding | | Interacting selectively and non-covalently with zinc (Zn) ions. |
biological process |
| GO:0007552 | | metamorphosis | | A biological process in which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's form or structure. Examples include the change from tadpole to frog, and the change from larva to adult. An example of this is found in Drosophila melanogaster. |
| GO:0006508 | | proteolysis | | The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. |
| GO:0009609 | | response to symbiotic bacterium | | 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 from a symbiotic bacterium, a bacterium living in close physical association with another organism. |
| GO:0007291 | | sperm individualization | | The resolution of the male germline syncytium or cyst into individual gametes by packaging each spermatid into its own plasma membrane. |
| GO:0007289 | | spermatid nucleus differentiation | | The specialization of the spermatid nucleus during the development of a spermatid into a mature male gamete competent for fertilization. |
cellular component |
| GO:0005576 | | extracellular region | | 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. |
| GO:0005615 | | extracellular space | | That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
