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:0000256|ARBA:ARBA00002714,
