Abstract | Acidic proteins are usually resistant to complete enzymic hydrolysis. The increasing number of "unusual" amino acids, which are unstable to acid hydrolysis, makes it necessary to have a method of enzymic hydrolysis applicable to all proteins. The complete hydrolysis of four acidic proteins by subtilisin plus leucine amino-peptidase plus prolidase followed by carboxypeptidase C, is described. Recoveries of amino acids were in excellent agreement with the expected content from the known sequences. |
