Data from: Para-aminosalicylic acid acts as an alternative substrate of folate metabolism in Mycobacterium tuberculosis

Sumit Chakraborty, Todd Gruber, , Helena I. Boshoff & Kyu Y. Rhee
Folate biosynthesis is an established anti-infective target, and the antifolate para-aminosalicylic acid (PAS) was one of the first anti-infectives introduced into clinical practice on the basis of target-based drug discovery. Fifty years later, PAS continues to be used to treat tuberculosis. PAS is assumed to inhibit dihydropteroate synthase (DHPS) in Mycobacterium tuberculosis by mimicking the substrate p-aminobenzoate (PABA). However, we found that sulfonamide inhibitors of DHPS inhibited growth of M. tuberculosis only weakly because of...
