VERFAHREN ZUR GEWINNUNG VON PROTEASE

摘要

Protease is recovered by reacting a first amino acid whose amino group is protected with a protective group with a second amino acid whose carboxyl group is protected with a protective group, in an aqueous medium in the presence of a protease to result a peptide synthesis to deposit the addition compound of a dipeptide and said second C-terminal protected amino acid; dissolving said addition compound into the aqueous medium by adding a polar organic solvent which is miscible with water and separating an insoluble material from the resulting suspension by a solid-liquid separation to isolate the protease.
