Characterization of mutationally altered dihydropteroate synthase and its ability to form a sulfonamide-containing dihydrofolate analog.
Among spontaneous mutants of Escherichia coli selected for resistance against sulfonamides, thermosensitive strains were found. These were shown to possess a changed dihydropteroate synthase (EC 2.5.1.15), which had a substantially higher Km value for its normal substrate, p-aminobenzoic acid, and a...
