P. AERUGINOSA FTSK MOTOR DOMAIN, DIMERIC
Overview
FtsK is a DNA translocase that coordinates chromosome segregation and cell, division in bacteria. In addition to its role as activator of XerCD, site-specific recombination, FtsK can translocate double-stranded DNA, (dsDNA) rapidly and directionally and reverse direction. We present, crystal structures of the FtsK motor domain monomer, showing that it has a, RecA-like core, the FtsK hexamer, and also showing that it is a ring with, a large central annulus and a dodecamer consisting of two hexamers, head, to head. Electron microscopy (EM) demonstrates the DNA-dependent existence, of hexamers in solution and shows that duplex DNA passes through the, middle of each ring. Comparison of FtsK monomer structures from two, different crystal forms highlights a conformational change that we propose, is the structural basis for a rotary inchworm mechanism of DNA, translocation.
