glutamate synthase activity glutamate synthase (ferredoxin) activity https://github.com/geneontology/go-ontology/issues/28526 https://github.com/geneontology/go-ontology/issues/31587 RHEA:12128 Catalysis of the reaction: 2 L-glutamate + 2 oxidized ferredoxin = L-glutamine + 2-oxoglutarate + 2 reduced ferredoxin + 2 H+. This is a two-step reaction: (a) L-glutamate + NH4+ = L-glutamine + H2O, (b) L-glutamate + 2 oxidized ferredoxin + H2O = NH4+ + 2-oxoglutarate + 2 reduced ferredoxin + 2 H+. glutamate synthase (ferredoxin-dependent) ferredoxin-dependent glutamate synthase activity ferredoxin-glutamate synthase activity MetaCyc:GLUTAMATE-SYNTHASE-FERREDOXIN-RXN molecular_function GO:0016041 EC:1.4.7.1 L-glutamate:ferredoxin oxidoreductase (transaminating) oxidoreductase activity, acting on the CH-NH2 group of donors, iron-sulfur protein as acceptor
