Metilamin dehidrogenaza (amicijanin) (EC 1.4.9.1, aminska dehidrogenaza, primarna aminska dehidrogenaza, amin: (akceptor) oksidoreduktaza (deaminacija), primarni-amin:(akceptor) oksidoreduktaza (deaminacija)) je enzim sa sistematskim imenom metilamin:amicijanin oksidoreduktaza (deaminacija).[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju:
- metilamin + H2O + amicijanin formaldehid + amonijak + redukovani amicijanin
Ovaj enzim sadrži triptofan triptofilhinon (TTQ) kofaktor. On oksiduje alifatične monoamine i diamine, histamin i etanolamin, a ne deluje na sekundarne i tercijarne amine, kvaternarne amonijum soli, i aromatične amine.
