N-methylalanine dehydrogenase

In enzymology, N-methylalanine dehydrogenase () is an enzyme that catalyzes the chemical reaction

The three substrates of this enzyme are N-methyl-L-alanine, water, and oxidised nicotinamide adenine dinucleotide phosphate (NADP⁺). Its products are pyruvic acid, methylamine, reduced NADPH, and a proton.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH₂ group of donors with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is N-methyl-L-alanine:NADP⁺ oxidoreductase (demethylating, deaminating).
