Streszczenie

Factor F430 (1), the prosthetic group of methyl-coenzyme M reductase, contains nickel ion in a macrocycle with N4 coordination.1 Observation of an ESR signal in whole cells of Methanobacterium thermoautotrophicum has been attributed to Factor F430 in the intact, active enzyme, and the g values and hyperfine
coupling constants of this signal are consistent with the presence of Ni1 (or Ni111).2 Reduction of factor F430 pentamethyl ester has been shown to yield a reduced species (g = 2.065,2.074,2.250) in which reduction is localized on the metal and the tetrahydrocorphin ring system is unaltered.3
