[https://www.uniprot.org/uniprot/CCA_ARCFU CCA_ARCFU] Catalyzes the addition and repair of the essential 3'-terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate.<ref>PMID:14592988</ref>
