Method for cleaving chimeric protein using processing enzyme

摘要

A chimeric protein is provided which comprises a target protein and has been designed so as to be easily cleaved by a processing enzyme, permitting a target protein to be efficiently recovered. The chimeric protein is represented by the following formula:A-L-Bwherein A represents a protective peptide; B represents a target peptide; and L represents a linker peptide having the sequence X1-X2-(Pro, Lys, or Arg)-Arg, wherein X1 and X2 represent any amino acid, in its C-terminal region and a domain rich in His in its N-terminal region.
