    The fungal pathogen Pneumocystis carinii causes a pneumonia which is an opportunistic infection of AIDS patients. Current therapy includes the dihydrofolate reductase (DHFR) inhibitor trimethoprim which is selective but only a relatively weak inhibitor of the enzyme for P. carinii. Determination of the three-dimensional structure of the enzyme should form the basis for design of more potent and selective therapeutic agents for treatment of the disease.
