RT conjugative type IV secretion system and host-cell interaction genes.";
RL Proc. Natl. Acad. Sci. U.S.A. 104:7981-7986(2007).
CC -!- FUNCTION: Accelerates the degradation of transcripts by removing
CC pyrophosphate from the 5'-end of triphosphorylated RNA, leading to a
CC more labile monophosphorylated state that can stimulate subsequent
CC ribonuclease cleavage. {ECO:0000255|HAMAP-Rule:MF_00298}.
CC -!- COFACTOR:
CC Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00298};
CC -!- SIMILARITY: Belongs to the Nudix hydrolase family. RppH subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00298}.
