Abstract
A new reversed-phase high-pressure liquid chromatography assay procedure for dihydropteroate synthetase (DHPS) that involves the elution of the enzyme incubation solution with a series of three solvents of decreasing polarity (ammonium phosphate buffer, 10% methanol, and 50% methanol) was designed. By this procedure DHPS was detected in Escherichia coli and Pneumocystis carinii with specific activities of 450 and 14 U/mg, respectively. A comparison of the effects of five sulfa drugs on P. carinii DHPS activity revealed that dapsone is the most potent of these drugs.Entities:
