I've put up a pull request to add @lnblum! 🎉

Would it be interesting to gather SIFTS from PDBe-KB? https://www.ebi.ac.uk/pdbe/covid-19
e.g. from https://www.ebi.ac.uk/pdbe/pdbe-kb/covid19/P0DTD1 ?

@KarelBerka yes this could make sense for interaction interfaces. Mainly so we can see information from one structure mapped on another one. It probably fits better in #8 though.

We do use SIFTS already in SWISS-MODEL to map PDB structures to the UniProt sequences but we don't extract any features/annotations from PDBe-KB (yet). We are in touch with the PDBe-KB team for other collaborations and I also contacted them last week so we can fix the mappings for the polyproteins. The problem there is that P0DTC1 is almost fully included in P0DTD1 (except a small peptide called nsp11) and hence any annotation for P0DTC1 should also be mapped on P0DTD1.

The interaction between the spike-protein and TMPRSS just came up on my radar. Seems relevant for the virus entry into the host cell (see also here) and looks like something where structural data can help...but we could need help in scanning the literature for it. Maybe IntAct will have more in future releases but otherwise, these two papers might be good entry points: https://www.biorxiv.org/content/10.1101/2020.02.08.926006v3.full and https://doi.org/10.1016/j.cell.2020.02.052.
