EC 1.2.7.5     
Accepted name: aldehyde ferredoxin oxidoreductase
Reaction: an aldehyde + H2O + 2 oxidized ferredoxin = a carboxylate + 2 H+ + 2 reduced ferredoxin
Other name(s): AOR
Systematic name: aldehyde:ferredoxin oxidoreductase
Comments: This is an oxygen-sensitive enzyme that contains tungsten-molybdopterin and iron-sulfur clusters. Catalyses the oxidation of aldehydes (including crotonaldehyde, acetaldehyde, formaldehyde and glyceraldehyde) to their corresponding acids. However, it does not oxidize glyceraldehyde 3-phosphate [see EC 1.2.7.6, glyceraldehyde-3-phosphate dehydrogenase (ferredoxin)]. Can use ferredoxin or methyl viologen but not NAD(P)+ as electron acceptor.
