|7,8-dihydropteroate:L-glutamate ligase (ADP).|
|Dihydrofolate synthetase-folylpolyglutamate synthetase.|
|Dihydropteroate:L-glutamate ligase (ADP-forming).|
|Folylpoly-(gamma-glutamate) synthetase-dihydrofolate synthase.|
|ATP + 7,8-dihydropteroate + L-glutamate <=> ADP + phosphate + 7,8-dihydropteroylglutamate|
- In some bacteria, a single protein catalyzes both this activity and
that of EC 22.214.171.124, the combined activity of which leads to the
formation of the coenzyme polyglutamated tetrahydropteroate
(H(4)PteGlu(n)), i.e. various tetrahydrofolates.
- In contrast, the activities are located on separate proteins in most
eukaryotes studied to date.
- This enzyme is reponsible for attaching the first glutamate residue
to dihydropteroate to form dihydrofolate and is present only in those
organisms that have the ability to synthesize tetrahydrofolate de
novo, e.g. plants, most bacteria, fungi and protozoa.
