Amine Dehydrogenase (), also known as methylamine dehydrogenase (MADH), is a tryptophan tryptophylquinone-dependent (TTQ-dependent) enzyme that catalyzes the oxidative deamination of a primary amine to an aldehyde and ammonia. The reaction occurs as follows: RCH2NH2 + H2O + acceptor → RCHO + NH3 + reduced acceptor Amine dehydrogenase possesses an α2β2 structure with each smaller β subunit possessing a TTQ protein cofactor. Amine dehydrogenase, studied in ''Paracoccus denitrificans'', at least transiently forms a ternary complex to catalyze methylamine-dependent cytochrome c-551i reduction. Within this complex, electrons are transferred from the TTQ cofactor of MADH to the Type 1 copper center of amicyanin, and then to the heme of the cytochrome. ==References== * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「amine dehydrogenase」の詳細全文を読む スポンサード リンク
