Chain A,B,C,D   (SYT_ECOLI | P0A8M3)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    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:0008144    drug binding    Interacting selectively and non-covalently with a drug, any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease.
    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:0016876    ligase activity, forming aminoacyl-tRNA and related compounds    Catalysis of the joining of an amino acid and a nucleic acid (usually tRNA) or poly(ribitol phosphate), with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. The reaction forms an aminoacyl-tRNA or a related compound.
    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: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:0004829    threonine-tRNA ligase activity    Catalysis of the reaction: ATP + L-threonine + tRNA(Thr) = AMP + diphosphate + L-threonyl-tRNA(Thr).
    GO:0000900    translation repressor activity, nucleic acid binding    Antagonizes the ribosome-mediated translation of mRNA into a polypeptide via direct binding (through a selective and non-covalent interaction) to nucleic acid.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0045947    negative regulation of translational initiation    Any process that stops, prevents, or reduces the frequency, rate or extent of translational initiation.
    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:0043039    tRNA aminoacylation    The chemical reactions and pathways by which the various amino acids become bonded to their corresponding tRNAs. The most common route for synthesis of aminoacyl tRNA is by the formation of an ester bond between the 3'-hydroxyl group of the most 3' adenosine of the tRNA, usually catalyzed by the cognate aminoacyl-tRNA ligase. A given aminoacyl-tRNA ligase aminoacylates all species of an isoaccepting group of tRNA molecules.
    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:0006435    threonyl-tRNA aminoacylation    The process of coupling threonine to threonyl-tRNA, catalyzed by threonyl-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: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.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
