WebStep-by-step solution. 100% (3 ratings) for this solution. Step 1 of 5. The inhibitor sulfonamide has structural resemblance with the substrate p -aminobenzoic acid (PABA). Thus, it would act as competitive inhibitor for the enzyme dihydropteroate synthase (DS). Competitive inhibitors are those that bind on the active site of the enzyme. WebDihydropteroate synthase inhibitors are drugs that inhibit the action of dihydropteroate synthase. They include sulfonamides, dapsone, and para-aminosalicylic acid. [1] In …
