Abstract:RNase E is a major ribonuclease for RNA metabolism in bacteria. Because it has a large substrate spectrum and poor substrate specificity, its activity must be well controlled under different conditions. Only a few regulators of RNase E are known in bacteria, limiting our understanding on the posttranscriptional regulatory mechanisms operating in these organisms. Here we show that, RebA, a protein universally present in cyanobacteria, interacts with RNase E in the filamentous cyanobacterium Anabaena PCC 7120. D… Show more
