Abstract excerpt
A three-disulfide intermediate, des-[65-72] RNase A, lacking the disulfide bond between Cys65 and Cys72, is formed in one of the rate-determining steps of the oxidative regeneration pathways of bovine pancreatic ribonuclease A (RNase A). An analog of this intermediate, [C65S, C72S] RNase A, has been characterized in terms of structure and thermodynamic stability. Triple-resonance NMR data were analyzed using an...
