Function
function
Functions in two distinct reactions of the de novo folate biosynthetic pathway. Catalyzes the addition of a glutamate residue to dihydropteroate (7,8-dihydropteroate or H2Pte) to form dihydrofolate (7,8-dihydrofolate monoglutamate or H2Pte-Glu). Also catalyzes successive additions of L-glutamate to tetrahydrofolate or 10-formyltetrahydrofolate or 5,10-methylenetetrahydrofolate, leading to folylpolyglutamate derivatives.
Catalytic activity
- (6R)-5,10-methylenetetrahydrofolyl-(gamma-L-Glu)(n) + ATP + L-glutamate = (6R)-5,10-methylenetetrahydrofolyl-(gamma-L-Glu)(n+1) + ADP + H+ + phosphate
(6R)-5,10-methylenetetrahydrofolyl-(γ-L-Glu)(n) RHEA-COMP:13257 + CHEBI:30616 + CHEBI:29985 = (6R)-5,10-methylenetetrahydrofolyl-(γ-L-Glu)(n+1) RHEA-COMP:13258 + CHEBI:456216 + CHEBI:15378 + CHEBI:43474
Pathway
Cofactor biosynthesis; tetrahydrofolate biosynthesis; 7,8-dihydrofolate from 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate and 4-aminobenzoate: step 2/2.
Cofactor biosynthesis; tetrahydrofolylpolyglutamate biosynthesis.
