    摘要: DNAS encoding the following proteins (A) or (B) which participate in the temperature sensitivity to surfactants of corynebacteria: (A) a protein having the amino acid sequence represented by SEQ ID NO:2 or a protein having the amino acid sequence represented by SEQ ID NO:2 wherein Leu at the 139-position is substituted by another amino acid residue excluding Pro and having a temperature sensitive DTSR activity; and (B) proteins derived from the above proteins (A) by substitution, deletion, insertion, addition or inversion of one or several amino acid residues except the one at the 139-position in the amino acid sequence represented by SEQ ID NO:2 and having the temperature sensitive DTSR activity.

    摘要: An object resides in controlling the retaining and dissociation of a gene extrachromosomally for efficient production of an objective substance in a fermentative manner.
    By culturing and growing a microorganism containing a plasmid carrying a gene disadvantageously functioning for the production of an objective enzyme and a temperature-sensitive replication origin, on which plasmid the functional gene is solely present, at a temperature at which the plasmid is replicable, and continuously culturing the microorganism at a temperature at which the plasmid is never replicable, to dissociate the plasmid from the cells and continue the culturing, the objective substance can efficiently be produced.
