Publication Abstract from PubMedFtsH is a cytoplasmic membrane-integrated, ATP-dependent metalloprotease, which processively degrades both cytoplasmic and membrane proteins in concert with unfolding. The FtsH protein is divided into the N-terminal transmembrane region and the larger C-terminal cytoplasmic region, which consists of an ATPase domain and a protease domain. We have determined the crystal structures of the Thermus thermophilus FtsH ATPase domain in the nucleotide-free and AMP-PNP- and ADP-bound states, in addition to the domain with the extra preceding segment. Combined with the mapping of the putative substrate binding region, these structures suggest that FtsH internally forms a hexameric ring structure, in which ATP binding could cause a conformational change to facilitate transport of substrates into the protease domain through the central pore.
