If you want to map the tiniest parts of a protein, you only have a few options: You can coax millions of individual protein molecules to align into crystals and analyze them using x-ray crystallography. Or you can flash-freeze copies of the protein and bombard them with electrons, a lower resolution method called cryo-electron microscopy (cryo-EM).
