DivK protein is present throughout the cell cycle. (A) Schematic diagram of C. crescentus cell cycle. Nonreplicating chromosomes are indicated as gray ovals and replicating chromosomes as gray theta structures. (B) Cell extracts from a synchronous population of cells were analyzed for the presence of DivK by immunoblot. Samples were taken every 20 min of a 120-min cell cycle, as indicated as cell cycle units.
