    • There are few, if any, known instances in which a biological signal is transmitted via a large conformational change through the body of a protein. We describe here a mutant of T4 lysozyme that was engineered to permit structural change at a distance. The design uses a tandem sequence repeat that makes it possible to transmit large-scale structural changes from one end of an alpha-helix to the other over a distance of 17-25 A ...

    There are few, if any, known instances in which a biological signal is transmitted via a large conformational change through the body of a protein. We describe here a mutant of T4 lysozyme that was engineered to permit structural change at a distance. The design uses a tandem sequence repeat that makes it possible to transmit large-scale structural changes from one end of an alpha-helix to the other over a distance of 17-25 A. The method should be of general applicability and may make it possible to introduce a mutation at one site in a protein that will induce large-scale changes in the structure at a spatially remote site.
