Sukcinat-semialdehid dehidrogenaza (acilacija) (EC 1.2.1.76, sukcinil-CoA reduktaza, koenzim-A-zavisni sukcinat-semialdehid dehidrogenaza) je enzim sa sistematskim imenom sukcinat semialdehid:NADP+ oksidoreduktaza (KoA-acilacija).[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju
- sukcinat semialdehid + KoA + NADP+ sukcinil-KoA + NADPH + H+
Ovaj enzim katalizuje NADPH-zavisnu redukciju sukcinil-KoA do sukcinat semialdehida. On je prisutan u Clostridium kluyveri, gde učestvuje u fermentaciji sukcinata, u Metallosphaera sedula, gde učestvuje u 3-hidroksipropionat/4-hidroksibutiratnom ciklusu, kao i u putu autotrofne fiksacije CO2 kod nekih termoacidofilnih arheja.
