context_page_description: Christian Boehmer Anfinsen Jr. was an American biochemist. He shared the 1972 Nobel Prize in Chemistry with Stanford Moore and William Howard Stein for work on ribonuclease, especially concerning the connection between the amino acid sequence and the biologically active conformation.
context_section_description: In 1950, the National Heart Institute, part of the National Institutes of Health in Bethesda, Maryland, recruited Anfinsen as chief of its laboratory of cell physiology. In 1954, a Rockefeller Foundation fellowship enabled Anfinsen to return to the Carlsberg Laboratory for a year and a Guggenheim Foundation fellowship allowed him to study at the Weizmann Institute of Science in Rehovot, Israel from 1958 to 1959. He was elected a Fellow of the American Academy of Arts and Sciences in 1958.
  In 1962, Anfinsen returned to Harvard Medical School as a visiting professor and was invited to become chair of the department of chemistry.  He was subsequently appointed chief of the laboratory of chemical biology at the National Institute of Arthritis and Metabolic Diseases (now the National Institute of Arthritis, Diabetes, and Digestive and Kidney Diseases), where he remained until 1981. In 1981, Anfinsen became a founding member of the World Cultural Council. From 1982 until his death in 1995, Anfinsen was professor of biophysical chemistry at Johns Hopkins.
  Anfinsen published more than 200 original articles, mostly in the area of the relationships between structure and function in proteins. He was also a pioneer of ideas in the area of nucleic acid compaction. In 1961, he showed that ribonuclease could be refolded after denaturation while preserving enzyme activity, thereby suggesting that all the information required by protein to adopt its final conformation is encoded in its amino-acid sequence. He belonged to the National Academy of Sciences (USA), the Royal Danish Academy of Sciences and Letters and the American Philosophical Society.
