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:0000256|RuleBase:RU361205}.
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:0000256|ARBA:ARBA00000012};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|ARBA:ARBA00001946,
CC ECO:0000256|RuleBase:RU361205};
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 {ECO:0000256|ARBA:ARBA00004763, ECO:0000256|RuleBase:RU361205}.
CC -!- SIMILARITY: Belongs to the DHPS family.
CC {ECO:0000256|RuleBase:RU361205}.
