Cys to ser mutations

WebQualitative results from these studies indicate that for the Ser130-->Cys mutation the large decrease in binding affinity is in part caused by steric effects, but also significantly by the differential work required to polarize the Cys thiol group relative to the Ser hydroxyl group. WebIn this study, we have employed a combined spectroscopic and computational approach to characterize three Cys-to-Ser (Cys --> Ser) mutants (C2S, C6S, and C2S/C6S NiSOD). …
