Accepted name: dissimilatory dimethyldisulfide reductase
Reaction: 2 methanethiol + NAD+ = dimethyl disulfide + NADH + H+
Systematic name: methanethiol:NAD+ oxidoreductase (dimethyl disulfide-forming)
Comments: The enzyme’s activity has been demonstrated in the bacterium Thiobacillus thioparus E6. The methanethiol formed is eventually oxidized to sulfate and carbon dioxide, and the latter assimilated for autotrophic growth.
