CC   -!- FUNCTION: Catalyzes the addition and repair of the essential 3'-
CC       terminal CCA sequence in tRNAs without using a nucleic acid template.
CC       Adds these three nucleotides in the order of C, C, and A to the tRNA
CC       nucleotide-73, using CTP and ATP as substrates and producing inorganic
CC       pyrophosphate. {ECO:0000255|HAMAP-Rule:MF_01263}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a tRNA precursor + ATP + 2 CTP = a tRNA with a 3' CCA end + 3
CC         diphosphate; Xref=Rhea:RHEA:14433, Rhea:RHEA-COMP:10465, Rhea:RHEA-
CC         COMP:10468, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:37563,
CC         ChEBI:CHEBI:74896, ChEBI:CHEBI:83071; EC=2.7.7.72;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01263};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01263};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01263}.
CC   -!- MISCELLANEOUS: A single active site specifically recognizes both ATP
CC       and CTP and is responsible for their addition. {ECO:0000255|HAMAP-
CC       Rule:MF_01263}.
CC   -!- SIMILARITY: Belongs to the tRNA nucleotidyltransferase/poly(A)
CC       polymerase family. Bacterial CCA-adding enzyme type 3 subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_01263}.
