organohalide respiration

traitmech:000204 · CLASS · PROPOSED

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

Trait evidence (3)

  • DOI:10.1098/rstb.2012.0322
    Organohalide respiration is an anaerobic bacterial respiratory process that uses halogenated hydrocarbons as terminal electron acceptors during electron transport-based energy conservation.

    Hug et al. define organohalide respiration as anaerobic electron-transport-based energy conservation with halogenated hydrocarbons as terminal electron acceptors.

  • DOI:10.1098/rstb.2012.0322
    Organohalide-respiring bacteria have been identified from multiple bacterial phyla

    Hug et al. support the record as a reusable bacterial respiration phenotype rather than a single-strain label.

  • DOI:10.1126/science.276.5318.1568
    Growth of strain 195 with H2 and tetrachloroethene as the electron donor and acceptor pair required extracts from mixed microbial cultures.

    Maymo-Gatell et al. support tetrachloroethene as a growth-coupled organohalide electron acceptor in Dehalococcoides mccartyi strain 195.

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 contains only obsolete Halogenated compound respiration and Organohalide respiration classes. Candidate reductive dehalogenase protein-family and enzyme terms are narrower than the whole-organism anaerobic respiration phenotype.

Curation history

  1. · MINTED_TRAITMECH_ID · codex

    Minted organohalide 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 organohalide/halogenated-compound respiration classes and the replacement placeholder is reserved in proposals/metpo_traitmech_v81.
