Limited proteolysis of p-chloromercuribenzoate-dissociated hemoglobin by trypsin.

p-Chloromercuribenzoate-treated hemoglobin was digested by trypsin. The hydrolysate was subjected to gel-filtration on Bio-Gel P-4 and Sephadex G-50 columns, ion-exchange chromatography on CM-Sephadex and DE 52 columns, and paper electrophoresis. Peptides obtained by this procedure were analyzed for amino acid compositions and amino-terminal amino acid… CONTINUE READING
