IntEnz Enzyme Nomenclature


Accepted name:
aldehyde dehydrogenase (FAD-independent)
Other names:
aldehyde oxidase
aldehyde oxidoreductase
Systematic name:
aldehyde:acceptor oxidoreductase (FAD-independent)




Belongs to the xanthine oxidase family of enzymes. The enzyme from Desulfovibrio sp. contains a molybdenum-molybdopterin-cytosine dinucleotide (MCD) complex and two types of [2Fe-2S] cluster per monomer, but does not contain FAD.
