Patent Title:
"Method of temperature-dependently controlling the expression amount of target protein"

It is found out that the expression amount of a protein can be temperature-dependently controlled by culturing a cell containing a mutant gene encoding the target protein, which is constructed by substituting at least one of amino aid-encoding codons in a gene encoding the target protein by a stop codon, and a factor participating in read through contained in Staphylococcus aureus. Use of this method of controlling the expression amount of a protein makes it possible to analyze the function of the protein, construct a temperature-sensitive strain in the case of requiring the target protein in the proliferation of a microorganism, and identify a protein essentially required for the proliferation. Moreover, an antimicrobial agent can be screened by using the temperature-sensitive strain thus constructed or targeting the proliferation protein thus identified.
