[Dynamics of intramembrane particles during proteolysis of certain membranes].
Freeze-fracture electron microscopy has been used to study the ultrastructure of proteolytic enzymes treated of the bovine photoreceptor membranes, the rat liver microsome ghosts and the rabbit sarcoplasmic reticulum membranes. The observed increase in the intramembranous particle number in the inner fracture face suggests transmembrane dipping of amphipathic integral proteins affected by the partial proteolysis.
