Allostery is a hallmark of cellular function and important in every biological system, but difficult to artificially mimic. Here, the authors report an approach to study aspects of allostery in artificial systems, using a DNA origami domino array structure which, upon binding of trigger DNA strands, undergoes a stepwise allosteric conformational change that can be monitored by a double FRET probe.
