The Cdv proteins constitute the cell division system of the Crenarchaea, a machinery closely related to the ESCRT system of eukaryotes. Using a combination of TEM imaging and biochemical assays, we here present an in vitro study of Metallosphaera sedula CdvB1, the Cdv protein that is believed to play a major role in the constricting ring that drives cell division in the Crenarchaea. We show that CdvB1 self‐assembles into filaments that are depolymerized by the Vps4‐homolog ATPase CdvC. Furthermore, we find that CdvB1 binds to negatively charged lipid membranes and can be detached from the membrane by the action of CdvC. Our findings provide novel insight into one of the main components of the archaeal cell division machinery. This study shows that the archaeal cell division protein CdvB1 can form filaments in vitro, and how these filaments are depolymerized by the AAA ATPase CdvC. We show that CdvB1 can bind to lipid membranes and can be detached from them by CdvC, providing new insights on the protein interactions of the archaeal Cdv system.
