| Abstrakt: | Bacterial cell division is the result of a productive round of the cell cycle to yield two daughter cells. The cell cycle is highly coordinated in Caulobacter crescentus where it is driven by a cell cycle gene-regulatory network that coordinates gene expression with the major cell cycle events such as chromosome replication and cell division. Recent ribosomes profiling data showed that 484 genes undergo changes in translation efficiency during the cell cycle, suggesting a broad role for translational control in cell cycle regulation. In this chapter, we focus on how to perform ribosome profiling to measure the translation efficiency across cellular mRNAs at key stages in the Caulobacter cell cycle. This methodology relies on the high-yield ludox gradient synchronization of Caulobacter cells followed by ribosome profiling to measure ribosome density and total RNA-seq to measure mRNA levels.
