a The ATP(+)-DNA(+)-MuB helix. Left: cryo-EM map; middle: cartoon display with the pitch parameters for DNA and MuB shown; right: top view. b Cryo-EM map of one helical turn containing eight MuB subunits and 24 bp dsDNA. c Atomic model of one helical turn containing eight MuB subunits and 24 bp dsDNA. DNA, MuBn, MuBn+1, MuBn+6, and MuBn+7 are shown in different colors.
