    摘要: The instant invention is directed to recombinant production of functionally active chymase. "Functionally active" as used herein refers to the ability to exhibit one or more functional activities of a full-length wild-type chymase protein. In a preferred aspect, a proteolytically inactive chymase fusion protein comprising a functionally active portion of a non-chymase protein joined to the amino-terminus of the chymase protein is produced, which, upon cleavage away of the non-chymase fusion protein portion, becomes proteolytically active. A refolding procedure for increasing yields of proteolytically active recombinant chymase is provided. The invention is further directed to use of the recombinant chymase thus produced for preparing chymase-specific antibodies.
