Elevation of RNase R in response to multiple stress conditions.

Abstract

Cells respond to adverse environmental conditions by synthesizing new proteins or elevating the levels of pre-existing ones that are needed to cope with the particular stress situation. We show here that Escherichia coli RNase R, a processive 3'-to5'-exoribonuclease, is dramatically increased in response to a variety of different stress conditions… (More)
