General annotation (Comments)

Function

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

Catalytic activity

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

Cofactor

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

Pathway

Cofactor biosynthesis; tetrahydrofolate biosynthesis; 7,8-dihydrofolate from 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate and 4-aminobenzoate: step 1/2.

Subunit structure

Homodimer By similarity.

Sequence similarities

Belongs to the DHPS family.

Contains 1 pterin-binding domain.
