The role of proteolysis in the Caulobacter crescentus cell cycle and development

Caulobacter crescentus cell cycle progression is implemented by oscillating global transcriptional regulators that establish temporal and spatial control of modular genetic subsystems during the cell cycle. The hierarchy of this regulatory circuit is established through a combination of gene expression control and regulated proteolysis. Recent results highlight the importance of spatial organization for controlled proteolysis in C. crescentus. (C) 2009 Elsevier Masson SAS. All rights reserved.
