molecular function |
| GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| GO:0019843 | | rRNA binding | | Interacting selectively and non-covalently with ribosomal RNA. |
| GO:0003735 | | structural constituent of ribosome | | The action of a molecule that contributes to the structural integrity of the ribosome. |
| GO:0000049 | | tRNA binding | | Interacting selectively and non-covalently with transfer RNA. |
biological process |
| GO:0042742 | | defense response to bacterium | | Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism. |
| GO:0006417 | | regulation of translation | | Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA. |
| GO:0006412 | | translation | | The cellular metabolic process in which a protein is formed, using the sequence of a mature mRNA or circRNA molecule to specify the sequence of amino acids in a polypeptide chain. Translation is mediated by the ribosome, and begins with the formation of a ternary complex between aminoacylated initiator methionine tRNA, GTP, and initiation factor 2, which subsequently associates with the small subunit of the ribosome and an mRNA or circRNA. Translation ends with the release of a polypeptide chain from the ribosome. |
cellular component |
| GO:0030529 | | intracellular ribonucleoprotein complex | | An intracellular macromolecular complex containing both protein and RNA molecules. |
| GO:0015934 | | large ribosomal subunit | | The larger of the two subunits of a ribosome. Two sites on the ribosomal large subunit are involved in translation, namely the aminoacyl site (A site) and peptidyl site (P site). |
| GO:0005840 | | ribosome | | An intracellular organelle, about 200 A in diameter, consisting of RNA and protein. It is the site of protein biosynthesis resulting from translation of messenger RNA (mRNA). It consists of two subunits, one large and one small, each containing only protein and RNA. Both the ribosome and its subunits are characterized by their sedimentation coefficients, expressed in Svedberg units (symbol: S). Hence, the prokaryotic ribosome (70S) comprises a large (50S) subunit and a small (30S) subunit, while the eukaryotic ribosome (80S) comprises a large (60S) subunit and a small (40S) subunit. Two sites on the ribosomal large subunit are involved in translation, namely the aminoacyl site (A site) and peptidyl site (P site). Ribosomes from prokaryotes, eukaryotes, mitochondria, and chloroplasts have characteristically distinct ribosomal proteins. |
