Human-derived Pneumocystis carinii dihydrofolate reductase (DHFR) was expressed in a Saccharomyces cerevisiae strain whose growth depends on complementation by this enzyme. We utilized a quantitative assay to measure the sensitivity of this yeast strain to DHFR inhibitors. This assay should be useful for identifying new inhibitors of human-derived P. carinii DHFR.
