Protein

Dihydropteroate synthase

Gene

folP

Organism
Shigella flexneri
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

DHPS catalyzes the formation of the immediate precursor of folic acid. It is implicated in resistance to sulfonamide By similarity.By similarity

Catalytic activityi

(2-amino-4-hydroxy-7,8-dihydropteridin-6-yl)methyl diphosphate + 4-aminobenzoate = diphosphate + dihydropteroate.

Cofactori

Binds 1 magnesium ion per subunit. Magnesium is required for activity, even if it interacts primarily with the substrate By similarity.By similarity
