title: Pushing the Boundaries of Chemical Protein Synthesis: The Case of Ubiquitin Chains and Polyubiquitinated Peptides and Proteins.
abstract: Chemical synthesis offers unique opportunities to prepare proteins with precise control of the atomic composition. Thanks to recent breakthroughs in synthetic methods, the preparation of large and complex proteins composed of 200-300 residues has now become possible. With these advances, a unique toolbox has been created to enable chemical biologists to investigate proteins that are difficult or even impossible to achieve otherwise, such as posttranslationally modified proteins and proteins composed of d-amino acids. In this review we describe the latest achievements in constructing protein conjugates of record sizes, such as those that are involved in the ubiquitin system.
