APS."; RL Nature 407:81-86(2000). CC -!- FUNCTION: Functions in two distinct reactions of the de novo folate CC biosynthetic pathway. Catalyzes the addition of a glutamate residue to CC dihydropteroate (7,8-dihydropteroate or H2Pte) to form dihydrofolate CC (7,8-dihydrofolate monoglutamate or H2Pte-Glu). Also catalyzes CC successive additions of L-glutamate to tetrahydrofolate or 10- CC formyltetrahydrofolate or 5,10-methylenetetrahydrofolate, leading to CC folylpolyglutamate derivatives. {ECO:0000250|UniProtKB:P08192}.
