Bionanomachine Evolution and Nanoecology
a story on real-time modular evolution in the bacterial flagellar motor and the nanoscopic anatomy of a bacteriophage attack

Life as we know it relies on complexes of interacting proteins that perform vital functions in the cell. Although comparative analysis shows that the origin and innovation of protein complexes involved modular integration of foreign subunits, experimental evidence of the capacity of evolution to achieve is lacking. I will present results from an evolution experiment that captured the integration of incompatible protein subunits into an existing complex. We replaced genes that encode an essential part of the bacterial flagellar motor—a nanoscopic rotary motor that powers bacterial swimming—with related genes that encode similar subunits in different species. The data reveal a remarkable combinatorial potential and show that evolution is able to overcome interaction conflicts at and beyond the compatibility horizon along parallel, step-wise mutational trajectories. Remarkably, bacteria that evolved compatibility with a foreign part often remain backward compatible with the original component. I will also discuss results from an ongoing project that is revealing the nanoscopic behavioral ecology of bacterial viruses as they select and kill their targets.
