CC   -!- FUNCTION: Catalyzes the condensation of para-aminobenzoate (pABA) with
CC       6-hydroxymethyl-7,8-dihydropterin diphosphate (DHPt-PP) to form 7,8-
CC       dihydropteroate (H2Pte), the immediate precursor of folate derivatives.
CC       {ECO:0000250|UniProtKB:P0AC13}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(7,8-dihydropterin-6-yl)methyl diphosphate + 4-aminobenzoate =
CC         7,8-dihydropteroate + diphosphate; Xref=Rhea:RHEA:19949,
CC         ChEBI:CHEBI:17836, ChEBI:CHEBI:17839, ChEBI:CHEBI:33019,
CC         ChEBI:CHEBI:72950; EC=2.5.1.15;
CC         Evidence={ECO:0000250|UniProtKB:P0AC13};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000250|UniProtKB:P0AC13};
CC   -!- PATHWAY: Cofactor biosynthesis; tetrahydrofolate biosynthesis; 7,8-
CC       dihydrofolate from 2-amino-4-hydroxy-6-hydroxymethyl-7,8-
CC       dihydropteridine diphosphate and 4-aminobenzoate: step 1/2.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the DHPS family. {ECO:0000305}.
