Abstract
The power of CPS, live! More than 90 attendees from around the world came together in Haifa to present and hear about cutting-edge science in protein chemistry, from advances in synthetic methods to applications in biology and medicine. The meeting was a powerful demonstration that chemical protein synthesis can provide otherwise unattainable insights into protein structure and function.

Abstract
We present a new approach for the covalent inhibition of HIV-1 integrase (IN) by an LEDGF/p75-derived peptide modified with an N-terminal succinimide group. The covalent inhibition is mediated by direct binding of the succinimide to the amine group of a lysine residue in IN. The peptide serves as a specific recognition sequence for the target protein, while the succinimide serves as the binding moiety. The combination of a readily synthesizable peptide precursor with easy and efficient binding to the target protein makes this approach a promising new strategy for designing lead compounds.
