Analytical Chemistry Techniques

Biochemists have used a combination of biochemistry & mass spec to “trap” new candidate substrates of the protease ClpXP to reveal how protein degradation is critical to cell cycle progression and bacterial development.
The bacterium Caulobacter crescentus (top image) was used for this work. It generates radically different cell types upon division. The ClpXP protease (bottom image) recognizes and destroys many protein substrates that allow Caulobacter to differentiate into these different cell types.
