Joel Sussman
Joel L. Sussman is an Israeli crystallographer best known for his studies on acetylcholinesterase, a key protein involved in transmission of nerve signals. He is Professor Emeritus of Structural Biology at the Weizmann Institute of Science in Rehovot and is Co-Director of the Israel Structural Proteomics Center.
Early life and education
Sussman was born in Philadelphia, Pennsylvania.In 1965, Sussman received his B.A. at Cornell University in math and physics. He received his PhD from MIT in biophysics in 1972, under Cyrus Levinthal. He postdocted at the Hebrew University of Jerusalem in 1972, with Yehuda Lapidot, and at Duke University in 1973-76 with Sung-Hou Kim.
Appointments and positions held
Sussman has been a Professor at the Weizmann Institute of Science since 1976.- 1984–85 – Head, Department of Structural Chemistry
- 1988–89 – Head, Kimmelman Center for Biomolecular Structure and Assembly
- 2002–14 – Incumbent of the Morton and Gladys Pickman Chair of Structural Biology
- 2016-now – Professor Emeritus
Scientific interests and contributions
Sussman was a pioneer of macromolecular refinement, developing CORELS and applying it to yeast tRNAphe. He subsequently determined the structures of 'bulge'-containing DNA fragments as models for insertion mutations.Sussman's current research focuses on nervous system proteins, especially acetylcholinesterase, whose 3D structure was first determined in his lab. This structure revealed:
- AChE is a prototype of the α/β hydrolase fold;
- π-cation interactions play a key role in binding of acetylcholine and ligands to AChE;
- Its ACh-binding site assisted in structure-based design of promising leads for novel anti-Alzheimer's drugs;
- Discovered that the cytoplasmic portion of 'cholinesterase-like adhesion molecules' are 'intrinsically disordered' that led to an algorithm, FoldIndex, for predicting whether a protein sequence will fold;
- The specific chemical and structural damage to proteins produced by synchrotron radiation, e.g. cleavage of a specific disulfide bond even at cryo temperatures.
