dimethyl sulfoxide respiration

traitmech:000201 · CLASS · PROPOSED

An anaerobic respiration in which an organism uses dimethyl sulfoxide as the terminal electron acceptor for energy conservation.

Trait evidence (4)

  • DOI:10.1073/pnas.0505959103
    one (SO1427-SO1432) is required for anaerobic respiration of DMSO

    Gralnick et al. identify the SO1427-SO1432 gene cluster required for Shewanella oneidensis MR-1 anaerobic respiration of dimethyl sulfoxide.

  • DOI:10.1073/pnas.0505959103
    DMSO respiration is an extracellular respiratory process

    Gralnick et al. support DMSO respiration as a bona fide respiratory process rather than an isolated reductase assay.

  • DOI:10.1111/1462-2920.15971
    M. thermoacetica can also use dimethyl sulfoxide as terminal electron acceptor

    Rosenbaum et al. support organism-level use of dimethyl sulfoxide as an anaerobic terminal electron acceptor.

  • DOI:10.1111/1462-2920.15971
    Membranes showed a DMSO reductase activity

    Rosenbaum et al. biochemically support an induced DMSO reductase activity in Moorella thermoacetica membranes.

CURATION TODO OPEN dimethyl-sulfoxide-respiration-xref-gap · raised by codex · 2026-09-15

Not yet attached to a section of this record — a curator sets attaches_to (e.g. causal_graphs#some_edge) so the gap shows beside the mechanism it concerns.

The pinned METPO snapshot has only an obsolete dimethyl sulfoxide respiration class. Candidate EC, Rhea, KEGG, and protein-family terms for DMSO reductase or DmsABC are narrower than the whole-organism anaerobic respiration phenotype.

Curation history

  1. · MINTED_TRAITMECH_ID · codex

    Minted dimethyl sulfoxide respiration as a DOI-backed anaerobic respiration TraitRecord after a repository-wide duplicate review covering ignored and hidden files; the local METPO snapshot has only obsolete sulfoxide respiration classes and the replacement placeholder is reserved in proposals/metpo_traitmech_v78.
