Ugljen-monoksid dehidrogenaza (akceptor) (EC 1.2.99.2, anaerobna ugljen monoksidna dehidrogenaza, ugljen monoksidna oksigenaza, ugljen-monoksidna dehidrogenaza, ugljen-monoksid:(akceptor) oksidoreduktaza) je enzim sa sistematskim imenom karbon-monoksid:akceptor oksidoreduktaza.[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju:

CO +H2O + A {\displaystyle \rightleftharpoons } CO2 + AH2

Ovaj enzim sadrži [Ni3Fe-4S] klaster i [4Fe-4S] klastere. On koristi mnoge elektronske akceptore, uključujući feredoksin, metil viologen, benzil viologen i flavine, a ne koristi piridinske nukleotide. Ovaj enzim formira deo membranskog multienzimskog kompleksa sa EC 1.12.99.6, hidrogenaza (akceptor), koji katalizuje sledeću reakciju:

CO + H2O {\displaystyle \rightleftharpoons } CO2 + H2.
