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

Chains	Enzyme Name	Description	Catalytic Residues
A	aldehyde oxidase M-CSA #968	Aldehyde oxidase is a member of the xanthine oxidase family. It is a complex molybdoenzyme containing a Mo cofactor (Moco), flavin adenine nucleotide (FAD) and two Fe₂S₂ clusters. The enzyme has broad substrate specificity and catalyses a wide range of reactions. This includes the oxidation of aldehydes and several N-heterocycles, as well as the reduction of some substrates. In the human liver, the enzyme plays an essential role in the detoxification of xenobiotics and contributes to the hepatic clearance of many other drugs.
