Abstract

Carbon and sulphur sequestration in bacterioplankton Marine microbes can utilize dimethylsulphoniopropionate as a source of carbon and sulphur, and the metabolic end products are either dimethylsulphide (DMS) or methanethiol. Despite the importance of these pathways in marine ecosystems, and the interest in DMS as a potential 'anti-greenhouse' gas, the enzymes involved in the pathway to methanethiol have remained unidentified. The missing components of the pathway have now been identified as three novel enzymatic reactions and two novel coenzyme A-containing intermediates. The genes encoding these enzymes have also been identified, and are shown to be present in many bacterioplankton, suggesting that the pathway is widespread in the ocean.
