  • NON-TOXIC PROTEASE HAVING IMPROVED PRODUCTIVITY
    Publication number: 20220251531
    Abstract: The present invention relates to a mutated non-toxic protease in which the amino acid cysteine (Cys) at position 430 of a non-toxic protease represented by the amino acid sequence of SEQ ID NO: 1 is substituted with an amino acid other than cysteine. According to the present invention, it is possible to recover a refolded non-toxic protease from an insoluble fraction from which the non-toxic protease was almost impossible to recover in the prior art, and thus it is possible to produce the non-toxic protease with significantly improved productivity.
