CCA tRNA nucleotidyltransferase

CCA tRNA nucleotidyltransferase (, "CCA-adding enzyme", "tRNA adenylyltransferase", "tRNA CCA-pyrophosphorylase", "tRNA-nucleotidyltransferase", "transfer-RNA nucleotidyltransferase", "transfer ribonucleic acid nucleotidyl transferase", "CTP(ATP):tRNA nucleotidyltransferase", "transfer ribonucleate adenylyltransferase", "transfer ribonucleate adenyltransferase", "transfer RNA adenylyltransferase", "transfer ribonucleate nucleotidyltransferase", "ATP (CTP):tRNA nucleotidyltransferase", "ribonucleic cytidylic cytidylic adenylic pyrophosphorylase", "transfer ribonucleic adenylyl (cytidylyl) transferase", "transfer ribonucleic-terminal trinucleotide nucleotidyltransferase", "transfer ribonucleate cytidylyltransferase", "ribonucleic cytidylyltransferase", "-C-C-A pyrophosphorylase", "ATP(CTP)-tRNA nucleotidyltransferase", "tRNA adenylyl(cytidylyl)transferase", "CTP:tRNA cytidylyltransferase") is an enzyme with systematic name "CTP,CTP,ATP:tRNA cytidylyl,cytidylyl,adenylyltransferase". This enzyme catalyses the following chemical reaction
The acylation of all tRNAs with an amino acid occurs at the terminal ribose of a 3' CCA sequence.
