- L-glutamine + 2-oxoglutarate + NADPH + H+ 2 L-glutamate + NADP+
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH2 group of donors with NAD+ or NADP+ as acceptor. This enzyme participates in glutamate metabolism and nitrogen metabolism. It has 5 cofactors: FAD, Iron, FMN, Sulfur, and Iron-sulfur.
The systematic name of this enzyme class is L-glutamate:NADP+ oxidoreductase (transaminating). Other names in common use include:
- glutamate (reduced nicotinamide adenine dinucleotide phosphate), synthase,
- glutamate synthase (NADPH),
- glutamate synthetase (NADP),
- glutamine amide-2-oxoglutarate aminotransferase (oxidoreductase, NADP),
- glutamine-ketoglutaric aminotransferase,
- L-glutamate synthase,
- L-glutamate synthetase,
- L-glutamine:2-oxoglutarate aminotransferase, NADPH oxidizing,
- NADPH-dependent glutamate synthase,
- NADPH-glutamate synthase, and
- NADPH-linked glutamate synthase.
