Abstract

A DNA segment contains a GAL1 promoter of Saccharomyces cerevisae linked to a gene other than the galoctokinase gene, for directing the expression of the gene within a yeast cell. A GAL1 promoter portion of Saccharomyces cerevisae is linked to a foreign DNA segment for use in expressing a desired protein. Yeast cells containing the GAL1 promoter linked to a foreign DNA segment are grown in a medium containing glucose, wherein the yeast cells metabolize the glucose and are permitted to express a polypeptide when galactose is present in the medium.
