Succinate dehydrogenase assembly factor 2 (SDHAF2) adds a flavin adenine dinucleotide (FAD) cofactor to SDHA to form an active SDHA flavoprotein. [alpha]-Ketoglutarate is converted by [alpha]-ketoglutarate dehydrogenase ([alpha]-KGDH) to succinyl-CoA, which in turn is converted by succinyl-CoA synthetase (SCS) to succinate.
