additional information | Escherichia coli | polynucleotide phosphorylase is essential for growth at low temperatures, while polymerization activity is not essential. RNase PH domains 1 and 2 of polynucleotide phosphorylase are important for its cold shock function, suggesting that the RNase activity of the enzyme is critical for its essential function at low temperature. Its polymerization activity is dispensable in its cold shock function. The RNase R , which is cold inducible, cannot complement the cold shock function of PNPase | ? | - |
