Cold shock induction of RNase R and its role in the maturation of the quality control mediator SsrA/tmRNA.

Molecular microbiology - 1 Nov 2003

Cairrão Fátima, Cruz Ana, Mori Hiroyuki, Arraiano Cecília Maria

Abstract excerpt

In this paper we show that RNase R is a cold shock protein that is induced seven- to eightfold by cold shock and that its expression is tightly regulated by temperature. Transcriptional studies reveal that the rnr gene is co-transcribed with flanking genes as an operon induced under cold shock. The induction of RNase R levels is mainly a result of the stabilization of the rnr transcripts. The transient stability...
