Abstract excerpt
Mutant human lysozymes (HLZ) lacking two disulfide bonds were constructed to study the importance of each disulfide bond on oxidative refolding. To avoid destabilization, a calcium-binding site was introduced. Five of the six species of two-disulfide mutants could be obtained with enzymatic activity. Based on the information obtained from refolding and unfolding experiments, the order of importance in oxidative...
