Thomas Arthur Steitz (August 23, 1940 – October 9, 2018[1]) was an American biochemist, a Sterling Professor of Molecular Biophysics and Biochemistry at Yale University, and investigator at the Howard Hughes Medical Institute, best known for his pioneering work on the ribosome.
Steitz was awarded the 2009 Nobel Prize in Chemistry along with Venkatraman Ramakrishnan and Ada Yonath "for studies of the structure and function of the ribosome".[2] Steitz also won the Gairdner International Award in 2007[3] "for his studies on the structure and function of the ribosome which showed that the peptidyl transferase (EC 2.3.2.12) was an RNA catalyzed reaction, and for revealing the mechanism of inhibition of this function by antibiotics".[4]
Born in Milwaukee, Wisconsin,[2] Steitz studied chemistry as an undergraduate at Lawrence University in Appleton, Wisconsin, graduating in 1962. In June 2010, the University renamed its chemistry building Thomas A. Steitz Hall of Science.[5]
He received a Ph.D. in biochemistry and molecular biology from Harvard University in 1966 where he worked under the direction of subsequent 1976 chemistry Nobel Prize winner William N. Lipscomb, Jr.While at Harvard, after the training task of determining the structure of the small molecule methyl ethylene phosphate, Steitz made contributions to determining the atomic structures of carboxypeptidase A (EC 3.4.17.1) and aspartate carbamoyltransferase (EC 2.1.3.2), each the largest atomic structure determined in its time.
Steitz did postdoctoral research as a Jane Coffin Childs Postdoctoral Fellow at the MRC Laboratory of Molecular Biology during 1967–1970.
Steitz briefly held an assistant professorship at the University of California, Berkeley, but he resigned on the grounds that the institution would not accept his wife Joan into a faculty position because she was a woman.[6]
Both Tom and Joan Steitz instead joined the Yale faculty in 1970, where he continued to work on cellular and structural biology. Steitz and Peter Moore determined the atomic structure of the large 50S ribosomal subunit using X-ray crystallography, and published their findings in Science in 2000.[7] In 2009, Steitz was awarded the Nobel Prize in Chemistry for his ribosome research.
He was also a Macy Fellow at the University of Göttingen during 1976–1977 and a Fairchild Scholar at the California Institute of Technology during 1984–1985.[3]
Steitz was also one of the founders of a company, Rib-X Pharmaceuticals, now Melinta Therapeutics for the development of new antibiotics based on the ribosome.
He enjoyed skiing, hiking, and gardening.[10]
Steitz was married to Joan A. Steitz, a distinguished molecular biologist who is also a Sterling Professor of Molecular Biophysics and Biochemistry at Yale. He lived with her in Branford, Connecticut and had one son, Jon, and two grandchildren, Adam and Maddy.[11] He died on October 9, 2018, of complications during treatment of pancreatic cancer.
