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. [1] [2]

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).
