Find your path : Methyl‐coenzyme M reductase (MCR, turquoise) reversibly catalyzes the reduction of methyl‐coenzyme M (methyl‐S‐CoM) with coenzyme B (CoB‐SH) to form methane and the heterodisulfide. Recently, spectroscopic methods were used to detect trapped intermediates in a stopped‐flow system, and CoM‐S‐Ni II was identified after half a turnover of the MCR reaction (F 430 =nickel porphinoid). This finding supports a methyl‐radical catalytic mechanism.
