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. Also shows phosphatase, 2'-nucleotidase and 2',3'-cyclic
CC phosphodiesterase activities. These phosphohydrolase activities are
CC probably involved in the repair of the tRNA 3'-CCA terminus degraded by
CC intracellular RNases. {ECO:0000255|HAMAP-Rule:MF_01261}.
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_01261};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01261};
CC Note=Magnesium is required for nucleotidyltransferase activity.
CC {ECO:0000255|HAMAP-Rule:MF_01261};
CC -!- COFACTOR:
CC Name=Ni(2+); Xref=ChEBI:CHEBI:49786;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01261};
CC Note=Nickel for phosphatase activity. {ECO:0000255|HAMAP-
CC Rule:MF_01261};
CC -!- SUBUNIT: Monomer. Can also form homodimers and oligomers.
CC {ECO:0000255|HAMAP-Rule:MF_01261}.
CC -!- DOMAIN: Comprises two domains: an N-terminal domain containing the
CC nucleotidyltransferase activity and a C-terminal HD domain associated
CC with both phosphodiesterase and phosphatase activities.
CC {ECO:0000255|HAMAP-Rule:MF_01261}.
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_01261}.
CC -!- SIMILARITY: Belongs to the tRNA nucleotidyltransferase/poly(A)
CC polymerase family. Bacterial CCA-adding enzyme type 1 subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01261}.
