|methylated-thiol--coenzyme M methyltransferase.
|coenzyme M + methanethiol <=> H(+) + hydrogen sulfide + methyl-coenzyme M|
- The enzyme, which is involved in methanogenesis from methylated
thiols, such as methane thiol, dimethyl sulfide,
and 3-(methylsulfanyl)propanoate, catalyzes two successive steps -
the transfer of a methyl group from the substrate to the cobalt
cofactor of a methylated-thiol-specific corrinoid protein (MtsB),
and the subsequent transfer of the methyl group from the corrinoid
protein to coenzyme M.
- With most other methanogenesis substrates this process is carried out
by two different enzymes (for example, EC 126.96.36.199 and EC 188.8.131.52).
- The cobalt is oxidized during methylation from the Co(I) state to the
Co(III) state, and is reduced back to the Co(I) form during
