organellar chromatophore thylakoid lumen

GO:0070117 · Membrane organelle · Subcellular region · Proposed

The volume enclosed by an organellar chromatophore thylakoid membrane. [GO:0070117]

Synonyms: Paulinella-type chromatophore thylakoid lumen

Part of: organellar chromatophore thylakoid (GO:0070116)

Xrefs: uniprot.location:SL-0355 — Organellar chromatophore thylakoid lumen

Taxonomic distribution

NCBITaxon:39716 Paulinella — VARIABLE: UniProt SL-0355 constrains organellar chromatophore thylakoid lumens to Paulinella species without asserting that every Paulinella species carries an organellar chromatophore. [uniprot.location:SL-0355 — Organellar chromatophore thylakoid lumen]

The organellar chromatophore thylakoid lumen is the Paulinella chromatophore thylakoid compartment enclosed by the thylakoid membrane.

Subject	Predicate	Object	Evidence
organellar chromatophore thylakoid membrane	encloses	organellar chromatophore thylakoid lumen	`GO:0070117` GO:0070117 defines the organellar chromatophore thylakoid lumen as the volume enclosed by an organellar chromatophore thylakoid membrane. `uniprot.location:SL-0355` — Organellar chromatophore thylakoid lumen UniProt SL-0355 describes the organellar chromatophore thylakoid lumen as the compartment bounded by the thylakoid membrane.

INTERPRETATION (RESOLVED): Keep the organellar chromatophore thylakoid membrane as the boundary of the organellar chromatophore thylakoid lumen rather than as a lumen component. GO:0070117 denotes the volume enclosed by an organellar chromatophore thylakoid membrane, whereas GO:0070118 denotes the lipid bilayer membrane that encloses that volume.

GO:0070117 Gene Ontology cellular-component term for the organellar chromatophore thylakoid lumen.
GO:0031978 Gene Ontology cellular-component term for plastid thylakoid lumen, the broader plastid thylakoid compartment.
GO:0070116 Gene Ontology cellular-component term for the organellar chromatophore thylakoid that this lumen is part of.
GO:0070118 Gene Ontology cellular-component term for the organellar chromatophore thylakoid membrane that encloses this lumen.
uniprot.location:SL-0355 — Organellar chromatophore thylakoid lumen UniProt Subcellular Location entry SL-0355 maps directly to GO:0070117, places it under plastid thylakoid lumen and organellar chromatophore thylakoid, and describes its Paulinella-specific taxonomic range.
