Dugolančana 3-oksoacil-CoA sintaza (EC 2.3.1.199, sintaza 3-ketoacil-KoA veoma dugog lanca, sintaza beta-ketoacil-KoA veoma dugog lanca, kondenzacijskii enzim, kodirana genima CUT1 CER6, FAE, KCS, ELO) je enzim sa sistematskim imenom malonil-KoA:dugolančana acil-KoA maloniltransferaza (dekarboksilacija i tioestarska-hidroliza)[1][2][3][4][5][6][7] Ovaj enzim katalizira sljedeću hemijsku reakciju
- acil-KoA veoma dugačkog lanca + malonil-CoA vrlo dugi lanac 3-oksoacil-CoA + CO2 + koenzim A
Ovaj enzim je prva komponenta elongaze, mikrosomskog proteinskog kompleksa odgovornog za produžavanje palmitoil-KoA i stearoil-KoA u acil sa veoma dugim lancima.
