Abstract
Regulation of RNA turnover is of utmost importance for controlling the concentration of transcripts and consequently cellular protein levels. Among the processes controlling RNA decay, small noncoding regulatory RNAs (sRNAs) have recently emerged as major new players. In this chapter, we describe and discuss protocols that can be used to measure sRNA concentration in vivo and to assess sRNA decay rates in Gram-negative bacteria. Precisely, we focus our analyses on the Escherichia coli Gram-negative bacterium as a model. The information described in this chapter provides a guideline to help develop a protocol in order to assess these important parameters and to identify RNA-processing enzymes involved in sRNA degradation processes.
