Dugolančana 3-oksoacil-KoA reduktaza (EC 1.1.1.330, dugolančana 3-ketoacil-KoA reduktaza, dugolančana beta-ketoacil-KoA reduktaza, KCR (gen), IFA38 (gen)) je enzim sa sistematskim imenom (3R)-3-hidroksiacil-KoA:NADP+ oksidoreduktaza.[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju
- veoma dugačak lanac (3R)-3-hidroksiacil-KoA + NADP+ veoma dugačak lanac 3-oksoacil-KoA + NADPH + H+
Ovaj enzim je druga komponenta elongaze, mikrozomalnog proteinskog kompleksa odgovornog za produžavanje palmitoil-KoA i stearoil-KoA (i njihovih modifikovanih formi) do dugolančanih konenzima A. On je aktivan na supstratima sa lancom dugim od C16 do C34, u zavisnosti od vrste, cf. EC 2.3.1.199, dugolančana 3-oksoacil-KoA sintaza, EC 4.2.1.134, dugolančana (3R)-3-hidroksiacil-[acil-nosilac protein] dehidrataza, i EC 1.3.1.93, dugolančana enoil-KoA reduktaza.
