arsenite oxidation

traitmech:000189 · CLASS · PROPOSED

A metabolism in which an organism enzymatically oxidizes arsenite to arsenate as an energy-generating electron donor or detoxification substrate.

Trait evidence (3)

  • DOI:10.3389/fmicb.2020.569282
    The biological oxidation of arsenite [As(III)] to arsenate [As(V)] is considered a strategy to reduce arsenic toxicity and provide energy

    Shi et al. review biological As(III)-to-As(V) oxidation as a microbial detoxification and energy-generating metabolism.

  • DOI:10.1128/AEM.66.1.92-97.2000
    A facultatively chemolithoautotrophic arsenite oxidizer (strain NT-26) was isolated from the arsenopyrite-containing gold mine at Pine Creek, Northern Territory, Australia.

    Santini et al. isolated the aerobic chemolithoautotrophic arsenite-oxidizing strain NT-26.

  • DOI:10.1186/s12866-024-03676-9
    Both BAW48 and BAS32 isolates demonstrated As(III) oxidation

    Hoque et al. report As(III)-oxidizing Achromobacter aegrifaciens isolates from arsenic-contaminated tubewell water and soil.

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 METPO:1000840 obsolete Arsenite oxidation. Potential external molecular function terms for arsenite oxidase activity are narrower than the organism-level As(III)-to-As(V) metabolism, and a future mechanism graph should distinguish aerobic AioBA oxidation from anaerobic ArxAB-mediated arsenite oxidation.

Curation history

  1. · MINTED_TRAITMECH_ID · codex

    Minted arsenite oxidation as a DOI-backed arsenic metabolism TraitRecord after a repository-wide duplicate review covering ignored and hidden files; the local METPO snapshot has only an obsolete Arsenite oxidation class and the replacement placeholder is reserved in proposals/metpo_traitmech_v66.
