DE   CCA tRNA nucleotidyltransferase.
AN   CCA-adding enzyme.
AN   ribonucleic cytidylic cytidylic adenylic pyrophosphorylase.
AN   transfer ribonucleic adenylyl (cytidylyl) transferase.
AN   transfer RNA adenylyltransferase.
AN   transfer-RNA nucleotidyltransferase.
AN   tRNA adenylyl(cytidylyl)transferase.
AN   tRNA CCA-diphosphorylase.
AN   tRNA cytidylyltransferase.
AN   tRNA-nucleotidyltransferase.
CA   a tRNA precursor + ATP + 2 CTP = a tRNA with a 3' CCA end +
CA   3 diphosphate.
CC   -!- The acylation of all tRNAs with an amino acid occurs at the terminal
CC       ribose of a 3' CCA sequence.
CC   -!- The CCA sequence is added to the tRNA precursor by stepwise
CC       nucleotide addition performed by a single enzyme that is ubiquitous
CC       in all living organisms.
CC   -!- Although the enzyme has the option of releasing the product after
CC       each addition, it prefers to stay bound to the product and proceed
CC       with the next addition.
CC   -!- Formerly EC 2.7.7.21 and EC 2.7.7.25.
