1H, 13C and 15N resonance assignments of RNA pyrophosphohydrolase RppH from Escherichia coli

The mRNA degradation is an important regulatory mechanism which controls gene expression by limiting the number of translation times. Previous studies demonstrated that this process is essential for organisms. Escherichia coli RNA pyrophosphohydrolase (RppH) is an enzyme that triggers mRNA degradation by removing the 5' pyrophosphate, which is a rate-determining step. In order to understand the molecular mechanism of the biological function, the structural information of RppH is required. Herein, we report the resonance assignments of (1)H, (15)N, (13)C atoms of the E. coli RppH.
