Abstract excerpt
The (3'-->5') exoribonuclease RNase R interacts with the endoribonuclease RNase E in the degradosome of the cold-adapted bacterium Pseudomonas syringae Lz4W. We now present evidence that the RNase R is essential for growth of the organism at low temperature (4 degrees C). Mutants of P. syringae with inactivated rnr gene (encoding RNase R) are cold-sensitive and die upon incubation at 4 degrees C, a phenotype that...
