tetrathionate respiration

traitmech:000200 · CLASS · PROPOSED

An anaerobic respiration in which an organism uses tetrathionate as the terminal electron acceptor and reduces it to thiosulfate for energy conservation.

CURATION TODO OPEN tetrathionate-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 no active organism-level class for tetrathionate respiration. Candidate EC, Rhea, and protein-family terms for tetrathionate reductase or the TtrA/TtrB/TtrC complex are narrower than the whole-organism anaerobic respiration phenotype.
