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}.
