molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0002161    aminoacyl-tRNA editing activity    The hydrolysis of an incorrectly aminoacylated tRNA.
    GO:0004812    aminoacyl-tRNA ligase activity    Catalysis of the formation of aminoacyl-tRNA from ATP, amino acid, and tRNA with the release of diphosphate and AMP.
    GO:0004822    isoleucine-tRNA ligase activity    Catalysis of the reaction: L-isoleucine + ATP + tRNA(Ile) = L-isoleucyl-tRNA(Ile) + AMP + diphosphate + 2 H(+).
    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:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    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:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0006428    isoleucyl-tRNA aminoacylation    The process of coupling isoleucine to isoleucyl-tRNA, catalyzed by isoleucyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.
    GO:0006450    regulation of translational fidelity    Any process that modulates the ability of the translational apparatus to interpret the genetic code.
    GO:0006418    tRNA aminoacylation for protein translation    The synthesis of aminoacyl tRNA by the formation of an ester bond between the 3'-hydroxyl group of the most 3' adenosine of the tRNA, to be used in ribosome-mediated polypeptide synthesis.
    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:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
