Abstract
The present invention relates to a DNA fragment having a promoter activity of PHO81 gene regulating the production of phosphatase, and which is obtainable from Saccharomyces cerevisiae.; a DNA fragment bearing a structural gene downstream from the above PHO81 promoter; a transformant containing a DNA fragment bearing the above PHO81 promoter; a transformant containing a DNA fragment bearing the above PHO81 promoter and a structural gene downstream from the PHO81 promoter; and a process for obtaining a gene product which includes culturing a transformant containing a DNA fragment bearing the above PHO81 promoter and a structural gene located downstream therefrom in a suitable medium until the gene product is formed and recovering the gene product from the culture. Pharmacologically important proteinous materials may be efficiently produced with the use of the above-described novel and potent promoter obtained from yeast which is a eukaryotic microorganism.
