Nickel-containing factor F430: chromophore of the methylreductase of Methanobacterium

Journal Article · · Proc. Natl. Acad. Sci. U.S.A.; (United States)

The yellow chromophore of the methyl-coenzyme M methylreductase of Methanobacterium thermoautotrophicum has been found to be the nickel-containing factor F/sub 430/. Treatment of /sup 63/Ni-labeled methylreductase with 80% aqueous methanol released the radiolabel as well as the yellow chromophore; both properties were associated with a single compound that was found to be identical to F/sub 430/, the stoichiometry being 1 mol of nickel per mol of F/sub 430/ and 2 mol o F/sub 430/ per mol of methylreductase.
