Abstract
Kex2 protease derivatives obtained by transforming methanol-assimilating with expression vectors containing DNA coding for any amino acid sequence which is an amino acid sequence of Kex2 protease wherein the N-terminus is the Met at position 1 and the C-terminus is one of the amino acids between positions 618 (inclusive) and 698 (inclusive), or a modification of that amino acid sequence, culturing the resulting transformants and recovering the derivatives from the cultures, as well as gene systems coding for the derivatives and a method for producing the Kex2 protease derivatives using the gene systems. Also, a method for excision of desired peptides using the Kex2 protease derivatives.
