Protein
Dihydropteroate synthase
Gene
sulA, spr0266
Organism
Streptococcus pneumoniae (strain ATCC BAA-255 / R6)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

DHPS catalyzes the formation of the immediate precursor of folic acid. It is implicated in resistance to sulfonamide.1 Publication

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.
