IUBMB Enzyme Nomenclature


Accepted name: secondary-alkyl amine dehydrogenase [NAD(P)+]

Reaction: a secondary-alkyl amine + H2O + NAD(P)+ = a ketone + NH3 + NAD(P)H + H+

Glossary: a secondary-alkyl amine = RCHNH2R'

Other name(s): AmDH (ambiguous); amine dehydrogenase (ambiguous)

Systematic name: secondary-alkyl amine:NAD(P)+ oxidoreductase (deaminating)

Comments: The enzyme has been shown to react preferentially with short-chain ketones such as cyclohexanone, primary amine groups attached to secondary alkyl groups, or D- and L-amino acids. It also reduces aldehydes to primary amines. Cosubstrate preference depends on the substrate.
