Ni | the niuckel porphinoid F-430 must be in the Ni(I) oxidation state for the enzyme to be active. The active enzyme exhibits an axial Ni(I)-based electron paramagnetic resonance signal and a UV-vis spectrum with an absorption maximum at 385 nM. This state is called the MCR-red1 state. When the temperature is lowered below 20°C the perecentage of MCR in the red2 state decreases and that in the red1 state increases. These changes with temperature are fully reversible. At most 50% of the enzyme is converted to the MCR-red2 state under all experimental conditions | Methanothermobacter marburgensis |
