Regulated expression of endonuclease EcoRI in Saccharomyces cerevisiae: nuclear entry and biological consequences.

abstract：:A mutation in the Escherichia coli dsbA gene (coding for a periplasmic disulfide oxidoreductase) reduces the rate of disulfide bond formation in the enzyme pullulanase and also reduces the rate at which the enzyme is secreted to the cell surface, as measured by protease accessibility. The enzyme did not become proteas...
