The idea of a bacterial cell as a disorganized sack is obsolete. We now know that bacteria have a diversity of organelles involved in essentially all aspects of cell function. Yet, the mechanisms governing organelle assembly, organization, and homeostasis remain unknown and virtually unstudied in bacteria. The cytoskeleton and motor proteins are well known for organizing the membrane-bound organelles of eukaryotes. But bacteria lack extensive membrane-bound organelles, cytoskeletal structures, and linear motors. Instead, bacterial organelles are largely protein-based and a widespread family of proteins, called ParA/MinD (A/D) ATPases, are responsible for their subcellular organization, but the mechanisms remain unclear. My lab is focused on the molecular mechanisms underlying the subcellular organization of bacterial organelles, of which I will discuss 3 research vignettes.
