Structure Motif Annotation: Mechanism and Catalytic Site Atlas M-CSA Database Homepage

Chains	Enzyme Name	Description	Catalytic Residues
A	aldehyde dehydrogenase (FAD-independent) M-CSA #105	The sulfate-reducing bacteria Desulfovibrio gigas synthesises a xanthine oxidase-related molybdenum-iron protein aldehyde oxidoreductase (Mop) which catalyses the oxidation of aldehydes to carboxylic acids. Mop contains two separate [2Fe-2S] clusters, and an Mo ion held by a pterin derivative called molybdopterin cytosine dinucleotide (together called the molybedenum cofactor, Mo-co).	Defined by 1 residue: GLU:A-869 \| Explore in 3D: M-CSA Motif Definition At least 2 residues must be present to support Structure Motif searching.
