Expression of the Pseudomonas gene coding for carboxypeptidase G2 in Saccharomyces cerevisiae

The Pseudomonas gene coding for carboxypeptidase G2 was introduced into Saccharomyces cerevisiae on an Escherichia coli/yeast shuttle vector pROG5. The level of enzyme activity obtained was independent of the orientation of the gene within the pBR322-derived tetracycline resistance gene of the vector, indicating that expression can occur from a Pseudomonas promoter in yeast.
