The two substrates of this enzyme are L-glutamic acid and oxidised ferredoxin. Its products are L-glutamine, α-ketoglutaric acid, reduced ferredoxin, and two protons.[1][2][3]
Classification
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH2 group of donors with an iron-sulfur protein as acceptor.
Nomenclature
The systematic name of this enzyme class is L-glutamate:ferredoxin oxidoreductase (transaminating). Other names in common use include:
- ferredoxin-dependent glutamate synthase,
- ferredoxin-glutamate synthase,
- glutamate synthase (ferredoxin-dependent), and
- ferredoxin-glutamine oxoglutarate aminotransferase (Fd-GOGAT).
Biological role
This enzyme participates in nitrogen metabolism. It has 5 cofactors: flavin adenine dinucleotide, iron, sulfur, iron-sulfur, and flavoprotein.
