ClpX inhibits FtsZ assembly in a manner that does not require its ATP hydrolysis-dependent chaperone activity.

Abstract:

:ClpX is a well-characterized bacterial chaperone that plays a role in many processes, including protein turnover and the remodeling of macromolecular complexes. All of these activities require ATP hydrolysis-dependent, ClpX-mediated protein unfolding. Here we used site-directed mutagenesis in combination with genetics and biochemistry to establish that ClpX inhibits assembly of the conserved division protein FtsZ through a noncanonical mechanism independent of its role as an ATP-dependent chaperone.
