Components

Component	Type	Part of / acts on	Grounding	Genes	Stoichiometry	Essential	Role
organellar chromatophore lipid bilayer	Lipid	part of	Reviewed label only (reviewed name; no accession asserted)			ESSENTIAL	Generic lipid-bilayer constituent of an organellar chromatophore membrane when the exact inner, outer, or thylakoid membrane identity is unspecified. `GO:0070112` GO:0070112 defines an organellar chromatophore membrane as a lipid bilayer surrounding an organellar chromatophore. `uniprot.location:SL-0352` — Organellar chromatophore membrane UniProt SL-0352 represents one of the organellar chromatophore membranes when the exact outer, inner, or thylakoid membrane assignment is unknown.

Taxonomic distribution

NCBITaxon:39716 Paulinella — VARIABLE: UniProt SL-0352 constrains organellar chromatophore membranes to Paulinella species without asserting that every Paulinella species carries an organellar chromatophore. [uniprot.location:SL-0352 — Organellar chromatophore membrane]

Mechanism graphs

Organellar chromatophore membrane scope (FUNCTION)

The generic organellar chromatophore membrane class covers inner, outer, and thylakoid membranes of the Paulinella organellar chromatophore when the exact membrane identity is unspecified.

organellar chromatophore membrane	part of	organellar chromatophore	`GO:0070111` GO places GO:0070112 as a part_of child of the organellar chromatophore term. `uniprot.location:SL-0352` — Organellar chromatophore membrane UniProt SL-0352 places the generic organellar chromatophore membrane under organellar chromatophore.

Discussions

INTERPRETATION (RESOLVED): Keep the generic organellar chromatophore membrane record separate from the exact inner, outer, and thylakoid membrane records. UniProt SL-0352 is used when the exact organellar chromatophore membrane is unknown, whereas GO:0070113, GO:0070114, and GO:0070118 identify exact inner, outer, and thylakoid membranes.
CURATION_TODO (OPEN): Resolve an exact source-neutral grounding for the generic lipid constituent of an organellar chromatophore membrane. The record is exactly grounded to GO:0070112 and UniProt SL-0352, but the generic lipid bilayer constituent is intentionally left as a reviewed-label-only component until an exact source-neutral lipid or membrane-constituent CURIE is curated.
