Strain LIG30, RT Isolated from Wet Tropical Forest Soil."; RL Submitted (MAR-2014) to the EMBL/GenBank/DDBJ databases. 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:0000256|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:0000256|HAMAP-Rule:MF_01261}; CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01261}; CC Note=Magnesium is required for nucleotidyltransferase activity. CC {ECO:0000256|HAMAP-Rule:MF_01261}; CC -!- COFACTOR: CC Name=Ni(2+); Xref=ChEBI:CHEBI:49786; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01261}; CC Note=Nickel for phosphatase activity. {ECO:0000256|HAMAP- CC Rule:MF_01261}; CC -!- SUBUNIT: Monomer. Can also form homodimers and oligomers. CC {ECO:0000256|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:0000256|HAMAP-Rule:MF_01261}. 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_01261}. CC -!- SIMILARITY: Belongs to the tRNA nucleotidyltransferase/poly(A) CC polymerase family. Bacterial CCA-adding enzyme type 1 subfamily. CC {ECO:0000256|HAMAP-Rule:MF_01261}. CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ CC whole genome shotgun (WGS) entry which is preliminary data. CC {ECO:0000313|EMBL:KDB06285.1}.
