title: Scanning force microscopy of the interaction events between a single molecule of heavy meromyosin and actin.
abstract: How close an approach is necessary for two interactive protein molecules to recognize each other before association? How strong a force field is exerted between two proteins at the recognition distance? How extensive are the association interfaces? How strong a force is necessary to pull the associated proteins apart? By means of atomic force microscopy at a truly single molecule level, these fundamental and intriguing questions were answered with the muscle proteins actin and myosin.
