CC         Highly stable from pH 0 to pH 12. {ECO:0000269|PubMed:27853299};
CC       Temperature dependence:
CC         Hyperthermostable. {ECO:0000269|PubMed:27853299};
CC   -!- SUBUNIT: Monomer. {ECO:0000269|PubMed:27853299}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:27853299}.
CC   -!- SIMILARITY: Belongs to the 7 kDa DNA-binding/endoribonuclease P2
CC       family. {ECO:0000305}.
