I would use the MSD database, which maintains a manually curated version
of the SwissProt to PDB mapping.

Strictly speeking, the above mapping gives you this. More realistically,
however, you can consider very close homologues to the above set as also
'solved'. Where you draw the line is a matter of requirement, but you can
get reasonable models (allegedly) at > 40% sequence identity, or
reasonable 'fold prediction' at much larger distances (see SUPERFAMILY for

It all depends on what you want to do.
