1.2.4.2	2-oxoglutarate + [dihydrolipoyllysine-residue succinyltransferase] lipoyllysine = [dihydrolipoyllysine-residue succinyltransferase] S-succinyldihydrolipoyllysine + CO2	the enzyme complex catalyzes the reaction : 2-oxoglutarate + CoA + NAD+--> succinyl-CoA + CO2 + NADH, the following partial reactions are catalyzed: 1. HOOC(CH2)2COCOOH + (thiamine diphosphate)-E1--> (HOOC(CH2)2 CHOH-thiamine-diphosphate)-E1 + CO2, 2. (HOOC(CH2)2CH OH-thiamine-diphosphate)-E1 + (LipS2)-E2--> (HOOC(CH)2 CO-(SLipSH))-E2 + (thiamine-diphosphate)-E1, 3. (HOOC(CH2)2CO-(SLipSH))-E2 + HSCoA--> (Lip(SH)2)-E2 + HOOC(CH2)2CO-SCoA, 4. (Lip(SH)2)-E2 + E3-FAD--> (LipS2)-E2 + reduced E3-FAD, 5. reduced E3-FAD + NAD+--> E3-FAD + NADH	348982, 348997, 348998, 348999, 349000, 349009, 349010, 349011, 349013, 349039, 349041
