Chains	Enzyme Name	Description	Catalytic Residues
A	betaine-aldehyde dehydrogenase M-CSA #100	Aldehyde dehydrogenases (ALDHs) catalyse the irreversible oxidation of a broad range of aldehydes to the corresponding acids. The substrates that ALDH work on include aliphatic and aromatic aldehydes, but also 2-enoic, 2-hydroxy, and 2-halogenated aldehydes. ALDHs are important components of cellular pathways that metabolise aldehydes and they have been ascribed important functions in cellular detoxification and defence systems.
