Methyl-coenzyme M reductase (MCR) catalyzes the chemical step of methane formation by methanogenic organisms. The reaction involves the two-electron reduction of CH{sub 3}S-CoM by N-7-mercaptoheptanoylthreoinine phosphate (CoB-SH). The authors have employed 35 GHz EPR and ENDOR spectroscopy to resolve the oxidation state of Ni in ox1, ox2 and red1 forms of MCR, isolated from methanobacterium thermoautotrophicum strain Marburg and prepared as described previously.
