0.1 mM, stimulates the rate of oxidation of NH2OH 2.6-fold and inhibits production of HNO2 by 40%
0.001 mM, stimulation of NH2OH utilization, stimulation at pH 6 and pH 9 is approximately 40% greater than at pH 7 and pH 8
one iron atom per subunit
enzyme contains 20 mol of iron but no other metals
one copper atom per subunit
the presence of Mn2+ results in decreased formation of NO and increased formation of N2O
