Peptides obtained by tryptic hydrolysis of performic acid-oxidized ribonuclease.
In the present study, the chemical structure of ribonuclease has been investigated by the use of trypsin as a reagent. for the hydrolysis of specific peptide bonds in the oxidized protein, and the resulting peptides have been separated and analyzed by ion exchange chromatography. The investigations of Anfinsen, Redfield, Choate, Page, and Carroll (3) have shown that ribonuclease consists of a s...
متن کاملPeptides obtained by peptic hydrolysis of performic acid-oxidized ribonuclease.
In a continuation of the structural studies on ribonuclease reported in earlier papers (l-3), the products resulting from the action of pepsin on performic acid-oxidized ribonuclease have been examined by means of ion exchange chromatography. Eight peptides have been isolated in purified form and their amino acid compositions have been determined. In a following communication (4), a partial str...
