1.14.13.128	Fe2+	preincubation of Ndm for 15 min with 1 mM Fe2+, followed by desalting, increases the iron content to 20.1 mol per mol hexameric N-demethylase component (Ndm) of the N-demethylase holoenzyme. After this treatment, Ndm specific activity increases about 6fold (when 50 mM Fe2+ is present in the enzyme reaction mixture). N-Demethylase component (Ndm) of the N-demethylase holoenzyme is deduced to be a Rieske [2Fe-2S]-domain containing non-haem iron oxygenase	
1.14.13.128	Fe2+	NdmA enzyme is a Rieske (2Fe-2S) non-heme iron monooxygenase	
1.14.13.128	Iron	a Rieske nonheme iron monooxygenase. The enzyme contains 2 mol of iron per mol of monomer	
1.14.13.128	Iron	contains a non-heme iron domain
