Ammonium monooxygenase from Nitrosomonas europaea

Ammonia monooxygenase (AMO) from Nitrosomonas europaea converts ammonia to hydroxylamine;

NH3 + O2 + cycAXred + 2 H+ → NH2OH + H2O + cycAXox

The whole operon containing amoA1, amoB1, amoC1 http://ecocyc.org/NEUR228410/NEW-IMAGE?type=MAPTICK&object=2238597/2241670&chromosome=CHROMOSOME-1&bp-range=2238597/2241670 link to Biocyc was extracted by colony PCR on a N. europaea culture.


Usage and Biology

AMO is an integral membrane protein composed of 3 subunits (amoA, amoB, amoC) and is first step in the enzymatic conversion of ammonia to nitrite in the nitrifying bacteria genus. The protein works in close relationship with cycA, cycX and Hydroxylamine oxidoreductase (HAO) in this process. HAO is providing 2 free electrons that are picked up and delivered to AMO by the cytochromes cycA and cycX. The electron from HAO is what makes AMO's work possible.

This part is experienced to slow down growth rates of E.coli substantially; likely because this is a heterologous expressed membrane protein and thereby disrupts E.coli membrane.
