1.14.99 Miscellaneous
1.14.99.39 ammonia monooxygenase
K10944 pmoA-amoA; methane/ammonia monooxygenase subunit A
The enzyme catalyses the first reaction in the pathway of ammonia oxidation to nitrite. It contains copper [1], iron [5] and possibly zinc [9]. The enzyme requires two electrons, which are derived indirectly from the quinone pool via a membrane-bound donor.
