the Brucella melitensis enzyme is fully active in vitro (20 mM Tris-HCl buffer, pH 8.0, with 100 mM NaCl, S-adenosyl-L-methionine (SAM), 5-aminolevulinic acid (ALA) and NADPH, aerobic, dark, 4°C) and the mononuclear non-heme iron is reducible by dithionite and then is able to react with NO as oxygen analogue in the presence of the substrate |

the Pseudomonas denitrificans enzyme is active in vivo but inactive in vitro (20 mM Tris-HCl buffer, pH 8.0, with 100 mM NaCl, S-adenosyl-L-methionine (SAM), 5-aminolevulinic acid (ALA) and NADPH, aerobic, dark, 4°C), the mononuclear non-heme iron is not reducible and probably rapidly inactivated outside the bacterium |
