Positioning of cellular components by the ParA/MinD family of ATPases

The ParA/MinD (A/D) family of ATPases spatially organize an array of genetic- and protein-based cellular cargos across the bacterial and archaeal domains of life. By far, the two best-studied members, and family namesake, are ParA and MinD, involved in bacterial DNA segregation and divisome positioning, respectively. ParA and MinD make protein waves on the nucleoid or membrane to segregate chromosomes and position the divisome. Less studied is the growing list of A/D ATPases widespread across bacteria and implicated in the subcellular organization of diverse protein-based complexes and organelles involved in myriad biological processes, from metabolism to pathogenesis. Here we describe mechanistic commonality, variation, and coordination among the most widespread family of positioning ATPases used in the subcellular organization of disparate cargos across bacteria and archaea.
