molecular function |
| GO:0005525 | | GTP binding | | Interacting selectively and non-covalently with GTP, guanosine triphosphate. |
| GO:0003924 | | GTPase activity | | Catalysis of the reaction: GTP + H2O = GDP + phosphate. |
| GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| GO:0000166 | | nucleotide binding | | Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
| 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:0019843 | | rRNA binding | | Interacting selectively and non-covalently with ribosomal RNA. |
| GO:0003746 | | translation elongation factor activity | | Functions in chain elongation during polypeptide synthesis at the ribosome. |
biological process |
| GO:1990145 | | maintenance of translational fidelity | | Suppression of the occurrence of translational errors, such as codon-anticodon mis-paring, during the process of translation of a protein using an mRNA template. |
| GO:0017183 | | peptidyl-diphthamide biosynthetic process from peptidyl-histidine | | The modification of peptidyl-histidine to 2'-(3-carboxamido-3-(trimethylammonio)propyl)-L-histidine, known as diphthamide, found in translation elongation factor EF-2. The process occurs in eukaryotes and archaea but not eubacteria. |
| GO:0045901 | | positive regulation of translational elongation | | Any process that activates or increases the frequency, rate or extent of translational elongation. |
| 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. |
| GO:0006414 | | translational elongation | | The successive addition of amino acid residues to a nascent polypeptide chain during protein biosynthesis. |
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: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. |
