molecular function |
| GO:0005524 | | ATP binding | | Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| GO:0042802 | | identical protein binding | | Interacting selectively and non-covalently with an identical protein or proteins. |
| GO:0016874 | | ligase activity | | Catalysis of the joining of two substances, or two groups within a single molecule, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. |
| GO:0016879 | | ligase activity, forming carbon-nitrogen bonds | | Catalysis of the joining of two molecules, or two groups within a single molecule, via a carbon-nitrogen bond, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. |
| 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:0032267 | | tRNA(Ile)-lysidine synthase activity | | Catalysis of the ligation of lysine onto the cytidine residue present at the wobble position (usually position 34) of an AUA-specific isoleucine tRNA, to form the derivative lysidine. This modification converts both the codon specificity of tRNA(Ile) from AUG to AUA and its amino acid specificity from methionine to isoleucine. |
biological process |
| GO:0006400 | | tRNA modification | | The covalent alteration of one or more nucleotides within a tRNA molecule to produce a tRNA molecule with a sequence that differs from that coded genetically. |
| GO:0008033 | | tRNA processing | | The process in which a pre-tRNA molecule is converted to a mature tRNA, ready for addition of an aminoacyl group. |
| GO:0002136 | | tRNA wobble base lysidine biosynthesis | | The process in which the carbonyl of cytosine at position 34 of a tRNA is post-transcriptionally replaced by lysine. |
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. |
