Support for residue mapping from UniProt to PDB structure?

[nabinchaulagain]

Is there any support for residue mapping from a sequence of a isoform on UniProt to a PDB structure?

I currently need it for a feature where I need to color parts of structure based on a feature where the user is allowed to color a certain range of sequences from uniprot.

For the case where you're looking at a public structure from the 'actual PDB', the uniprot mappings are available in lots of places (I think SIFTs is the canonical mapping), including in the mmCIF file itself: https://www.ebi.ac.uk/pdbe/news/sifts-data-now-included-pdbe-mmcif-files

A nice addition would be if NGL picked this up (in its parsing of the mmCIF file).

For the general case of "some protein file" (e.g. not necessarily public and without annotations) you might need to run a quick blastp vs some likely subset of uniprot (e.g. human proteome if you're mainly dealing with human structures) and manage the mapping yourself.
