Metilendiureja deaminaza (EC 3.5.3.21, metilindiurejaza) je enzim sa sistematskim imenom metilindiureja aminohidrolaza.[1] Ovaj enzim katalizuje sledeću hemijsku reakciju
- metilindiureja + 2H2O N-(hidroksimetil)ureja + 2 NH3 + CO2 (sveukupna reakcija)
- (1a) metilindiureja + H2O N-(karboksiaminometil)ureja + NH3
- (1b) N-(karboksiaminometil)ureja N-(aminometil)ureja + CO2 (spontana reakcija)
- (1c) N-(aminometil)ureja + H2O N-(hidroksimetil)ureja + NH3 (spontana reakcija)
Metilindiureja se hidrolizuje i dekarboksiluje čime se formira aminisana metilureja.
