Hemerythrin (also spelled haemerythrin; Ancient Greek: αἷμα, romanized: haîma, lit. 'blood', Ancient Greek: ἐρυθρός, romanized: erythrós, lit. 'red') is an oligomeric protein responsible for oxygen (O2) transport in the marine invertebrate phyla of priapulids, brachiopods, and in the annelid worm clades Magelona and Sipuncula. Myohemerythrin is a…

How Hemerythrin connects Entity context
Entity context groups extracted connections by relationship type. Counts show recurrence in the analyzed source; the examples are research signals, not claims about importance.
The extracted context around Hemerythrin shows recurring relationship patterns in the source. For example, Hemerythrin → Bath, Berven, Brenner, Bruseth, Characterization, Chem, CS1, Dioxygen, FEBS, Jensen, Karlsen, Larsen, Lillehaug, Methylococcus, PMID, Ramsevik, Rev, S2CID, Stenkamp Another extracted example is Hemerythrin → Cryptococcus, Cupriavidus, E3, F-box, Filobasidiella, H-HExxE-H-HxxxE, H-HxxxE-H-HxxxE, H-HxxxE-HxxxH-HxxxxD, Hemerythrin/HHE, HHE, It, More, Nereis, NorA, ScdA, Staphylococcus, The, This. Use these groups to spot repeated connection types before inspecting the individual relationships.
Relationships are represented as Subject → Predicate → Object triples. Confidence describes extraction strength, not the real-world importance of a relationship; lower-confidence rows may be contextual rather than explicit.
TTTA extracted 63 structured relationships around Hemerythrin. Examples in this analysis include Hemerythrin → AlphaFold → IPR035938 and Hemerythrin → AlphaFold → PF01814. The table shows each extracted connection, where it came from and its confidence.

Related concept clusters Concept neighborhoods
Concept neighborhoods group terms that sit near one another in the extracted graph. They are useful for discovering adjacent language and context, but proximity does not by itself imply a factual relationship.
The concept neighborhoods around Hemerythrin bring nearby vocabulary together. In this analysis, examples include O2, Dioxygen and Domain. Use the clusters to find adjacent concepts and terminology that may deserve separate research.

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Hemerythrin, one of the stronger structural bridges in this analysis connects Hemerythrin with Overview. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.

Source & methodology
TTTA analyzes the structure around Hemerythrin to surface related topics, entities, relationships, concept neighborhoods and bridge connections. Use the map to explore areas such as Hemerythrin/HHE cation-binding domain, Overview & O2 binding mechanism, including less central topics that may reveal useful research gaps. Automatically extracted connections are research leads rather than rewritten encyclopedia content.
