Comments Composition [PUB_0334]. DNA-binding 8 SSB monomers bind per 145 nt [PUB_0637]. Clusters of 8 SSB monomers, or beads, are spaced by 30 nt [PUB_0637]. Thus the spacing between SSB beads is 1 per 175 nt [PUB_0637]. Footprint of a single SSB is 5 nt [PUB_0734]. This value must be larger than dnaPolymeraseElongationRate.
