WebSulfonamides (sulfa drugs) are drugs that are derived from sulfanilamide, a sulfur-containing chemical.Most sulfonamides are antibiotics, but some are prescribed for treating ulcerative colitis.Sulfonamide antibiotics work by disrupting the production of dihydrofolic acid, a form of folic acid that bacteria and human cells use for producing proteins. WebIn bacteria, the enzyme dihydropterate synthase (DHPS) converts the molecule para-aminobenzoic acid (PABA) into dihydrofolic acid (DHF) which is an intermediate in folic acid synthesis. Which of the following is the substrate …
