Protein attributes

Sequence length	156 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Accelerates the degradation of transcripts by removing pyrophosphate from the 5'-end of triphosphorylated RNA, leading to a more labile monophosphorylated state that can stimulate subsequent ribonuclease cleavage By similarity. HAMAP MF_00298
Cofactor	Divalent ions By similarity. HAMAP MF_00298
Sequence similarities	Belongs to the Nudix hydrolase family. RppH subfamily. Contains 1 nudix hydrolase domain.
