Methylamine dehydrogenase (amicyanin) (EC 1.4.9.1, amine dehydrogenase, primary-amine dehydrogenase) is an enzyme with systematic name methylamine:amicyanin oxidoreductase (deaminating).[1][2][3][4][5] This enzyme catalyses the following chemical reaction:

methylamine + H2O + amicyanin formaldehyde + ammonia + reduced amicyanin

This enzyme contains tryptophan tryptophylquinone (TTQ) co-factor.
