organellar chromatophore thylakoid lipid bilayer	Lipid	part of	Reviewed label only (reviewed name; no accession asserted)			ESSENTIAL	Internal organellar chromatophore thylakoid lipid bilayer that bounds the thylakoid lumen and houses light-reaction complexes. `GO:0070118` GO:0070118 defines the organellar chromatophore thylakoid membrane as the lipid bilayer membrane of an organellar chromatophore thylakoid. `uniprot.location:SL-0356` — Organellar chromatophore thylakoid membrane UniProt Subcellular Location SL-0356 maps directly to GO:0070118 and describes the same internal photosynthetic membrane system.

NCBITaxon:39716 Paulinella — VARIABLE: UniProt SL-0356 constrains the organellar chromatophore thylakoid membrane to Paulinella species without asserting that every Paulinella species carries this membrane. [uniprot.location:SL-0356 — Organellar chromatophore thylakoid membrane]

photosynthesis, light reaction GO:0019684 — The organellar chromatophore thylakoid membrane houses complexes that carry out the light reactions of photosynthesis.
- uniprot.location:SL-0356 — Organellar chromatophore thylakoid membrane UniProt SL-0356 describes the membrane as the internal system housing complexes for the light reactions of photosynthesis.

The organellar chromatophore thylakoid membrane bounds the thylakoid lumen and supports photosynthetic light-reaction complexes.

Subject	Predicate	Object	Evidence
organellar chromatophore thylakoid membrane	bounds	organellar chromatophore thylakoid lumen	`GO:0070117` GO:0070117 defines the lumen as the volume enclosed by an organellar chromatophore thylakoid membrane.
organellar chromatophore thylakoid membrane	supports	photosynthesis, light reaction	`GO:0070118` GO:0070118 defines the membrane as the lipid bilayer of an organellar chromatophore thylakoid. `uniprot.location:SL-0356` — Organellar chromatophore thylakoid membrane UniProt SL-0356 describes the membrane as housing the complexes that carry out photosynthetic light reactions.

CURATION_TODO (OPEN): Resolve an exact source-neutral grounding for the lipid constituent of the organellar chromatophore thylakoid membrane. The record is exactly grounded to GO:0070118 and UniProt SL-0356, but the lipid bilayer constituent is intentionally left as a reviewed-label-only component until an exact source-neutral lipid or membrane-constituent CURIE is curated.
