how to get genomic position from protein pdb ID+AA residue position within the protein

Question

[lait]

Hi,

We sequence trios at our lab, and we would like to check if any of the variants lie within protein-protein interaction sites. I found this database called PiSite, a database for protein-protein interaction sites.

For such sites, I can get the AA residues position within a protein, in addition to the protein PDB ID.

With this information in hand, how is it possible to get the genomic position of those specific AA residues ? anyone aware of programming libraries that can help in this case?

The solution I came up with is to download multiple databases and translate coordinates from one database to the other.
