WebThe meager evidence from crystallography adds to all the other evidence pointing to highly specific spatial relationships in binding. Thus, although p-chloromercuribenzene sulfonate (PCMBS) binds to crystals of sperm whale myoglobin (Watson et al., 1964), and analysis of x-ray diffraction data shows the negative sulfonate end of the molecule close to the end … WebWilliam Thomas Astbury (1898–1961) William Thomas Astbury studied the structures of fibrous materials, including fabrics, proteins, and deoxyribonucleic acid, or DNA, in England during the twentieth century. Astbury employed X-ray crystallography, a technique in which scientists use X-rays to learn about the molecular structures of materials.
