Caulobacter polar microdomain
This illustration, titled "Caulobacter Polar Microdomain," shows the aquatic bacterium Caulobacter crescentus, which has a two-step life cycle: It's born as a free-swimming "swarmer,” shown here, and develops into an immobile "stalked" cell. In both stages, poles created at either end of the cell control development of stage-specific structures. The protein "PopZ" creates a compartment in the poles (yellow) to keep in what's needed for this development and keep out other components.
The illustration was created by David S. Goodsell, a research professor at Rutgers University and scientific outreach lead for PDB-101, the education and outreach arm of the U.S. National Science Foundation-supported (grant DBI 2321666) Protein Data Bank, an online portal for exploring the world of proteins and nucleic acids.
