8283	RFE: improve chain info for fusion proteins (list multiple UniProt IDs)	Elaine Meng	Tom Goddard	"It would really help to understand fusion/insertion proteins if the chain info table shown when you initially fetch/open a structure could give more than one UniProt name or ID per chain.

Example is 2rh1, fusion protein of GPCR and T4 lysozyme (often used to stabilize the crystal to allow structure determination).  Chain info table only gives the UniProt name for the GPCR, not the lysozyme part.

Where I'm usually trying to go is to find the precise boundary(ies) between the two proteins.  You can't really do it by opening the uniprot sequence and associating the protein, because it will usually associate a few extra residues on the ends but call them mismatches.

The RCSB page for this structure shows both of the UniProt identifiers, and both of them are in the mmCIF file."	enhancement	closed	moderate		Sequence		fixed		Eric Pettersen				all	ChimeraX
