Cyrus Homi Chothia (b. 19 Feb. 1942) FRS is an emeritus scientist at the Medical Research Council (MRC) Laboratory of Molecular Biology (LMB) and emeritus fellow of Wolfson College, Cambridge.
Chothia was educated at Alleyn's School, then went to study at the Durham University graduating with a Bachelor of Science degree in 1965. Chothia then completed a Master of Science degree at Birkbeck College in 1967 and a PhD in from University College London under the supervision of Peter Pauling, the son of Linus Pauling.
After his Ph.D. Chothia worked in the Laboratory of Molecular Biology (LMB) for three years. He then worked with Michael Levitt at the Weizmann Institute of Science  followed by two years with Joel Janin at the Institut Pasteur in Paris.
In 1992 he proposed that most proteins are built of domains that come from a small number of families. He collaborated with Alexey Murzin, Steven Brenner and Tim Hubbard to create the Structural Classification of Proteins (SCOP) database, a periodic table for all known protein structures. With Julian Gough to create the SUPERFAMILY database which uses Hidden Markov models to identify protein sequences that are related to those of known structures.
|“||Dr Chothia has shown how the amino sequences of proteins determine their structure, function and evolution. From an analysis of their structural regularities, he has developed a classification of protein structures that is now in general use. His picture of protein evolution suggests how proteins diverge and gain new functions. He has helped us to understand how their apparently limited set of slightly different structures allow immunoglobin to recognise an almost limitless variety of different antigens.||”|
