General Information

General Information Comment Organism
physiological function polynucleotide phosphorylase and RNase PH interact to support sRNA stability, activity, and base pairing in exponential and stationary growth conditions. They facilitate the stability and regulatory function of the sRNAs RyhB, CyaR, and MicA during exponential growth. Polynucleotide phosphorylase may contribute to pairing between RyhB and its mRNA targets. During stationary growth, each sRNA responds differently to the absence or presence of PNPase and RNase PH. Polynucleotide phosphorylase and RNase PH stabilize only Hfq-bound sRNAs Escherichia coli
