EC 1.14.99.39

Accepted name: ammonia monooxygenase

Reaction: ammonia + AH2 + O2 = NH2OH + A + H2O

Other name(s): AMO

Systematic name: ammonia,hydrogen-donor:oxygen oxidoreductase (hydroxylating)

Comments: Contains copper and possibly nonheme iron. The donor is membrane-bound. Electrons are derived indirectly from ubiquinol.
