Identification
Name: RNA pyrophosphohydrolase
Synonyms:
  • (Di)nucleoside polyphosphate hydrolase
  • Ap5A pyrophosphatase
Gene Name: rppH
Enzyme Class: Not Available
Biological Properties
General Function: Involved in hydrolase activity
Specific Function: Master regulator of 5'-dependent mRNA decay. 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. Preferentially hydrolyzes diadenosine penta-phosphate with ATP as one of the reaction products. Also able to hydrolyze diadenosine hexa- and tetra-phosphate. Has no activity on diadenosine tri-phosphate, ADP-ribose, NADH and UDP- glucose. In the meningitis causing strain E.coli K1, has been shown to play a role in HBMEC (human brain microvascular endothelial cells) invasion in vitro
