molecular function |
| GO:0004177 | | aminopeptidase activity | | Catalysis of the hydrolysis of N-terminal amino acid residues from in a polypeptide chain. |
| 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:0070006 | | metalloaminopeptidase activity | | Catalysis of the hydrolysis of N-terminal amino acid residues from a polypeptide chain 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:0008235 | | metalloexopeptidase activity | | Catalysis of the hydrolysis of a peptide bond not more than three residues from the N- or C-terminus of a polypeptide chain 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. |
biological process |
| GO:0031365 | | N-terminal protein amino acid modification | | The alteration of the N-terminal amino acid residue in a protein. |
| GO:0018206 | | peptidyl-methionine modification | | The modification of peptidyl-methionine. |
| GO:0070084 | | protein initiator methionine removal | | The protein modification process in which the translation-initiating methionine or formylmethionine residue is removed from a protein. |
| GO:0016485 | | protein processing | | Any protein maturation process achieved by the cleavage of a peptide bond or bonds within a protein. Protein maturation is the process leading to the attainment of the full functional capacity of a protein. |
| GO:0006508 | | proteolysis | | The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. |
| GO:0022400 | | regulation of rhodopsin mediated signaling pathway | | Any process that modulates the frequency, rate or extent of rhodopsin-mediated signaling. |
cellular component |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| GO:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
