CC -!- FUNCTION: Counteracts the endogenous Pycsar antiviral defense system.
CC Phosphodiesterase that enables metal-dependent hydrolysis of host
CC cyclic nucleotide Pycsar defense signals such as cCMP and cUMP.
CC {ECO:0000256|ARBA:ARBA00034301}.
CC -!- FUNCTION: Zinc phosphodiesterase, which displays some tRNA 3'-
CC processing endonuclease activity. Probably involved in tRNA maturation,
CC by removing a 3'-trailer from precursor tRNA. {ECO:0000256|HAMAP-
CC Rule:MF_01818}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3',5'-cyclic CMP + H2O = CMP + H(+); Xref=Rhea:RHEA:72675,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:58003,
CC ChEBI:CHEBI:60377; Evidence={ECO:0000256|ARBA:ARBA00034221};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:72676;
CC Evidence={ECO:0000256|ARBA:ARBA00034221};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3',5'-cyclic UMP + H2O = H(+) + UMP; Xref=Rhea:RHEA:70575,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:57865,
CC ChEBI:CHEBI:184387; Evidence={ECO:0000256|ARBA:ARBA00034227};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:70576;
CC Evidence={ECO:0000256|ARBA:ARBA00034227};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endonucleolytic cleavage of RNA, removing extra 3' nucleotides
CC from tRNA precursor, generating 3' termini of tRNAs. A 3'-hydroxy
CC group is left at the tRNA terminus and a 5'-phosphoryl group is left
CC at the trailer molecule.; EC=3.1.26.11; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01818};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01818};
CC Note=Binds 2 Zn(2+) ions. {ECO:0000256|HAMAP-Rule:MF_01818};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_01818}.
CC -!- SIMILARITY: Belongs to the RNase Z family. {ECO:0000256|HAMAP-
CC Rule:MF_01818}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
