Abstract: Reverse phase chromatography of complex mixtures of lens protein digests, in the presence and absence of dithiothreitol, provides a rapid method of identifying sequences involved in disulfide bonding. The results of this analysis using the endoprotease lys-C have demonstrated that beta A3/A1 crystallin from cataractous lenses contains an intermolecular disulfide bond involving cysteine residues 170 and 185.
