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...

متن کاملDegradative studies on vasopressin and performic acid-oxidized vasopressin.
Application of the t,echnique of counter-current distribution t,o the purificat,ion of the pressor principle from beef post’erior pituitary glands has afforded preparations with potencies of over 400 pressor units per mg. (1). Analysis of hydrolysates of such preparations for constituent amino acids by chromatography on starch has shown that they contain approximately equimolar amounts of the e...
متن کاملThe sequence of the amino acid residues in performic acid-oxidized ribonuclease.
In previous studies (3) a partial structural formula for oxidized bovine ribonuclease was derived from knowledge of the peptides formed by the action of trypsin (4), chymotrypsin (3), and pepsin (5). The results showed the order in which the peptides were linked to one another to form the single peptide chain of 124 amino acid residues present in the parent molecule. The preparation of milligra...
