From: Oligomerization and ATP stimulate condensin-mediated DNA compaction
Loop-capture and loop-enlargement functions of condensin. In the single-DNA experiments condensin can mediate “loop capture” events which generate sharp jumps down in extension (A→B) of size roughly 200 nm (600 bp). Following loop capture, length can be absorbed into the loop gradually (B→C), possibly in an ATP-dependent manner, and possibly preferentially for condensin multimers (only monomers are sketched here). The step-like and smooth extrusion dynamics are highly idealized in this sketch.
