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. tRNA 3'-terminal CCA addition is required both for tRNA
CC processing and repair. Also involved in tRNA surveillance by mediating
CC tandem CCA addition to generate a CCACCA at the 3' terminus of unstable
CC tRNAs. While stable tRNAs receive only 3'-terminal CCA, unstable tRNAs
CC are marked with CCACCA and rapidly degraded. {ECO:0000256|HAMAP-
CC 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 -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01263}.
CC -!- MISCELLANEOUS: A single active site specifically recognizes both ATP
CC and CTP and is responsible for their addition. {ECO:0000256|HAMAP-
CC Rule:MF_01263}.
CC -!- SIMILARITY: Belongs to the tRNA nucleotidyltransferase/poly(A)
CC polymerase family. Bacterial CCA-adding enzyme type 3 subfamily.
