Evidence for a nickel-containing carbon monoxide dehydrogenase in Methanobrevibacter arboriphilicus.
In growing cultures of Methanobrevibacter arboriphilicus (Methanobrevibacter arboriphilus), the synthesis of active carbon monoxide dehydrogenase required nickel. The 21-fold-purified enzyme from 63Ni-labeled cells of M. arboriphilicus comigrated with 63Ni during gel filtration. These results provide evidence that the carbon monoxide dehydrogenase of methanogens is a nickel protein.
