Published: February 2005

PDI is an enzyme that acts as a chaperone, shufflase, and oxidase during the folding of disulfide-containing proteins. The ability of aromatic thiols to increase the activity of PDI-catalyzed protein folding over that of the standard thiol glutathione (GSH) was measured. 4-Mercaptobenzoic acid (ArSH) increased the activity of PDI by a factor of three.
