酵素学において、ジヒドロ葉酸合成酵素（EC 6.3.2.12）は、化学反応を触媒する酵素である。
- ATP + 7,8-dihydropteroate + L-glutamate ADP + phosphate + 7,8-dihydropteroylglutamate
この酵素の3つの基質はATP、7,8-ジヒドロテロエート、L-グルタミン酸であり、3つの産物はADP、リン酸、7,8-ジヒドロテロイルグルタミン酸である。
This enzyme belongs to the family of ligases, specifically those forming carbon-nitrogen bonds as acid-D-amino-acid ligases (peptide synthases). The systematic name of this enzyme class is 7,8-dihydropteroate:L-glutamate ligase (ADP-forming). Other names in common use include dihydrofolate synthetase, 7,8-dihydrofolate synthetase, H2-folate synthetase, 7,8-dihydropteroate:L-glutamate ligase (ADP), dihydrofolate synthetase-folylpolyglutamate synthetase, folylpoly-(gamma-glutamate) synthetase-dihydrofolate synthase, FHFS, FHFS/FPGS, dihydropteroate:L-glutamate ligase (ADP-forming), and DHFS. This enzyme participates in folate biosynthesis.
Structural studies
As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 1W78, 1W7K, and 2BMB.
