1.2.7.3 | 2-oxoglutarate + CoA + oxidized ferredoxin | no activity with oxalacetate, oxomalonate, 2-oxoisocaproate, or phosphoenolpyruvate. The enzyme reacts with 2-oxobutyrate, pyruvate, and 2-oxoisovalerate at an activity level of less than 0.4 to 0.7% relative to that with 2-oxoglutarate. The enzyme uses 2-oxoglutarate, coenzyme A, and one of several electron acceptors in substrate amounts (ferredoxin isolated from Hydrogenobacter thermophilus, flavin adenine dinucleotide, flavin mononucleotide, or methyl viologen). NAD+, NADP+, and ferredoxins from Chlorella spp. and Clostridium pasteurianum are ineffective | Hydrogenobacter thermophilus | succinyl-CoA + CO2 + reduced ferredoxin | - |
