Identification of native and non-native structure in kinetic folding intermediates of apomyoglobin.

Abstract

Site-directed mutagenesis has been used to probe the interactions that stabilize the equilibrium and burst phase kinetic intermediates formed by apomyoglobin. Nine bulky hydrophobic residues in the A, E, G and H helices were replaced by alanine, and the effects on protein stability and kinetic folding pathways were determined. Hydrogen exchange pulse… (More)
