Stephen Kent (chemist)

Stephen B. H. Kent (born December 12, 1945, in Wellington, New Zealand) is a professor at the University of Chicago. While professor at the Scripps Research Institute in the early 1990s he pioneered modern ligation methods for the total chemical synthesis of proteins. He was the inventor of native chemical ligation together with his student Philip Dawson. His laboratory experimentally demonstrated the principle that chemical synthesis of a protein's polypeptide chain using mirror-image amino acids after folding results in a mirror-image protein molecule which, if an enzyme, will catalyze a chemical reaction with mirror-image stereospecificity. At the University of Chicago Kent and his junior colleagues pioneered the elucidation of protein structures by quasi-racemic & racemic crystallography.
