EC 1.2.7.5 Details

show Brenda entry

EC number

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

CAS registry number

138066-90-7

Comment

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.
