Mapping the transition state and pathway of protein folding by protein engineering

Nature. 1989 Jul 13;340(6229):122-6. doi: 10.1038/340122a0.

Abstract

In the transition state for unfolding of barnase, the hydrophobic core between the major alpha-helix and beta-sheet is somewhat weakened, the C terminus of the major helix is largely intact but its N terminus is exposed and a major loop has been invaded by solvent.
