Aldehid feredoksin oksidoreduktaza (EC 1.2.7.5, AOR) je enzim sa sistematskim imenom aldehid:feredoksin oksidoreduktaza.[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju
- aldehid +H2O + 2 oksidovani feredoksin karboksilat + 2 H+ + 2 redukovani feredoksin
Ovaj enzim je senzitivan na kiseonik. On sadrži volfram-molibdopterin i gvožđe-sumporne klastere. Ovaj enzim katalizuje oksidaciju aldehida (uključujući krotonaldehid, acetaldehid, formaldehid i gliceraldehid) do njihovih korespondirajućih kiselina. On ne oksiduje gliceraldehid 3-fosfat, cf. EC 1.2.7.6, gliceraldehid-3-fosfat dehidrogenaza (feredoksin). Ovaj enzim može da koristi feredoksin ili metil viologen, ali ne NAD(P)+ kao elektronski akceptor.
