Chain A   (CCA_ARCFU | O28126)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0052929    ATP:3'-cytidine-cytidine-tRNA adenylyltransferase activity    Catalysis of the reaction: a tRNA with a 3' CC end + ATP = a tRNA with a 3' CCA end + diphosphate.
    GO:0052928    CTP:3'-cytidine-tRNA cytidylyltransferase activity    Catalysis of the reaction: a tRNA with a 3' cytidine + CTP = a tRNA with a 3' CC end + diphosphate.
    GO:0052927    CTP:tRNA cytidylyltransferase activity    Catalysis of the reaction: a tRNA precursor + CTP = a tRNA with a 3' cytidine end + diphosphate.
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0000287    magnesium ion binding    Interacting selectively and non-covalently with magnesium (Mg) ions.
    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:0016779    nucleotidyltransferase activity    Catalysis of the transfer of a nucleotidyl group to a reactant.
    GO:0004810    tRNA adenylyltransferase activity    Catalysis of the reaction: ATP + tRNA(n) = diphosphate + tRNA(n+1).
    GO:0000049    tRNA binding    Interacting selectively and non-covalently with transfer RNA.
    GO:0016437    tRNA cytidylyltransferase activity    Catalysis of the reaction: CTP + tRNA(n) = diphosphate + tRNA(n+1).
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0031123    RNA 3'-end processing    Any process involved in forming the mature 3' end of an RNA molecule.
    GO:0042245    RNA repair    Any process that results in the repair of damaged RNA.
    GO:0001680    tRNA 3'-terminal CCA addition    Post-transcriptional addition of the terminal 3' CCA sequence to a tRNA which does not encode this sequence within the primary transcript. CCA addition proceeds by the sequential addition of CTP, CTP, and then ATP to the 3' end of the tRNA, yielding a diphosphate with each nucleotide addition.
    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.
