Dorothy Mary Crowfoot Hodgkin OM FRS HonFRSC [9] [10] (née Crowfoot; 12 May 1910 – 29 July 1994) was a Nobel Prize-winning English chemist who advanced the technique of X-ray crystallography to determine the structure of biomolecules, which became essential for structural biology.
A powder X-ray diffractometer in motion. X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions.
Pauling's approach combined methods and results from X-ray crystallography, molecular model building, and quantum chemistry. His discoveries inspired the work of Rosalind Franklin , James Watson , Francis Crick , and Maurice Wilkins on the structure of DNA , which in turn made it possible for geneticists to crack the DNA code of all organisms.
Crick was in the right place, in the right frame of mind, at the right time (1949), to join Max Perutz's project at the University of Cambridge, and he began to work on the X-ray crystallography of proteins. [30] X-ray crystallography theoretically offered the opportunity to reveal the molecular structure of large molecules like proteins and ...
David Blow (1931–2004), British biophysicist who helped develop X-ray crystallography of proteins; Baruch Blumberg (Barry Blumberg) (1925–2011), US physician and Nobel Prize-winner on hepatitis B; Julia Bodmer (1934–2001), British geneticist, key figure in discovery and definition of the HLA system
The discovery of X-rays and electrons in the last decade of the 19th century enabled the determination of crystal structures on the atomic scale, which brought about the modern era of crystallography. The first X-ray diffraction experiment was conducted in 1912 by Max von Laue, [7] while electron diffraction was first realized in 1927 in the ...
Firstly they showed that X-ray crystallography could be used to reveal the regular, ordered structure of DNA – an insight which laid the foundations for the later work of Maurice Wilkins and Rosalind Franklin, [1] after which the structure of DNA was identified by Francis Crick and James D. Watson in 1953. Secondly, they did this work at a ...
The most prominent techniques are X-ray crystallography, nuclear magnetic resonance, and electron microscopy. Through the discovery of X-rays and its applications to protein crystals, structural biology was revolutionized, as now scientists could obtain the three-dimensional structures of biological molecules in atomic detail.
