Open Access Theses & Dissertations
Protein Disulfide Isomerase is a highly evolved oxidoreductase enzyme that has the capability of oxidizing, reducing, and isomerizing disulfides in substrate. PDI is organized into several domains denoted a, b, b', a' and c. These domains are believed to have different functions but all must be present for full PDI activity. In this manuscript we recorded the ability of PDI b' to catalyze oxidative folding in fully reduced RNase A. We also examined competition between thiol-disulfide shuffling and conformational folding by PDI. This competition creates a rough effect of a highly efficient enzyme in two different substrates: RNase A and …
