Protein attributes

Sequence length	178 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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.
Cofactor	Divalent ions By similarity.
Sequence similarities	Belongs to the Nudix hydrolase family. RppH subfamily. Contains 1 nudix hydrolase domain.
