Long-Distance conformational changes in a protein engineered by modulated sequence duplication
Overview
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.
