The Internal Organization of Mycobacterial Partition Assembly: Does the DNA Wrap a Protein Core?
Figure 2
Hypothetical three-dimensional organizations of the partition assembly. Two topologically alternative scenarios can be proposed: (a) a “DNA inside, protein outside” model or (b) a “DNA outside, protein inside” model. The DNA is shown as black line, proteins are shown as grey beads. These models can be described as composite cylinders for low-resolution solution scattering experiments. Anticipated shapes at the protein and the DNA match-point for both models (as narrower or hollow cylinders) are shown as cartoons (case I–IV). The handedness and scale are arbitrary. We note that solution scattering cannot distinguish between the left- and the right-handed senses.
