Look into ingest of RHEA into RTX-KG2

[saramsey]

From Stephanie Won's Slack post:

I uncovered some prefixes missing from RTX-KG2 when node synonymizing the MicrobiomeKG data: RHEA, EUPATH, GTOPB, UNII, PANTHER.FAMILY, PANTHER.PATHWAY.

1. RHEA seems to be from here. These are novel groups of CHEBI identifiers that react or combine to produce other CHEBI identifiers. I would like the ARAX team’s insight on handling these CHEBI proxies (?) identifiers and whether including them would be a good idea.
2. EUPATH prefix enteries are from EuPathDB,
3. GTOPB is from here,
4. UNII looks like FDA drug identifiers…
