This view shows enzymes only for those organisms listed below, in the list of taxa known to possess the pathway. If an enzyme name is shown in bold, there is experimental evidence for this enzymatic activity.
Synonyms: DMSO degradation

Some taxa known to possess this pathway include : Arthrobacter methylotrophus, Arthrobacter sulfonivorans, Halobacterium sp. NRC-1, Hyphomicrobium denitrificans WU-K217, Hyphomicrobium sp. EG, Hyphomicrobium sp. S, Hyphomicrobium sulfonivorans
dimethyl sulfoxide (DMSO) is naturally present in significant amounts (1-200 nM) in ocean surface waters, probably originating from marine phytoplankton [Andreae80]. In addition, DMSO is widely used in various industries since it dissolves many organic and inorganic substances. In Japan alone a total of 5000 tons of DMSO is produced per year for use in various industries. Much of the DMSO accumulates in wastewater, where it has toxic effects on many organisms [MurakamiNitta02].
DMSO-reducing capacity is widespread among aerobic and anaerobic bacteria, plants, and animals [Distefano64, Yen77]. Some organisms, including Hyphomicrobium sp. S and Hyphomicrobium denitrificans WU-K217, are able to utilize DMSO aerobically as the sole source of carbon, by the use of an NADH-dependent dimethylsulfoxide reductase [DeBont81, MurakamiNitta02]. A similar organism, Hyphomicrobium sp. EG, could do the same using an NADPH-dependent enzyme [Suylen86, Suylen86a].
Other organisms, such as Halobacterium sp. NRC-1 and Escherichia coli K-12, can not utilze DMSO as a carbon source, but are able to utilize it as as an alternative terminal electron acceptor (in the absence of nitrate), using the complex dimethyl sulfoxide reductase [Zinder78, Moore89, Schwalb03, Muller05] (see formate to dimethyl sulfoxide electron transfer).
