    Ammonia oxidation, as the first step of nitrification, constitutes a critical process in the global nitrogen cycle. However, fundamental knowledge of its key enzyme, the copper-dependent ammonia monooxygenase, is lacking, in particular for the environmentally abundant ammonia-oxidizing archaea (AOA) …
  3. ammonia via the integral membrane protein complex ammo-nia monooxygenase (AMO) [2, 3]. While ammonia-oxidizing bacteria (AOB) were first discovered over 125 years ago [4] and have been extensively studied, this biological process was also detected in the archaeal domain in the last 20 years [5-7]. Ammonia-oxidizing archaea (AOA) have gained ...

    Modeling and in-gel cross-link approaches support an overall protomer structure similar to the distantly related bacterial particulate methane monooxygenase but also reveals clear differences in extracellular domains of the enzyme, opening avenues for further structure-function studies of this ecologically important nitrification complex. Ammonia oxidation, as the first step of nitrification ...

    Nitrification is a key microbial process in the global nitrogen cycle. Autotrophic archaeal and bacterial ammonia oxidizers (AOA and AOB, respectively) and comammox bacteria, which carry out the complete oxidation of ammonia to nitrate (1, 2), initiate nitrification through the oxidation of ammonia (NH 3) to hydroxylamine (NH 2 OH), a reaction catalyzed by ammonia monooxygenase (AMO).
  8. Ammonia oxidation as the first step of nitrification constitutes a critical process in the global nitrogen cycle. However, fundamental knowledge of its key enzyme, the copper-dependent ammonia monooxygenase is lacking, in particular for the environmentally abundant ammonia oxidizing archaea (AOA). Here, the structure of the enzyme is investigated by blue-native gel electrophoresis and ...
