Close-packed α-helices in proteins can move relative to each other by up to ∼1.5 Å by small conformational adjustments in the side-chains that form the interface between them. Such relative helix motions facilitate the long-range transmission of conformational change, examples of which are the closure of clefts between domains in enzymes, and allosteric transitions.
