  Artificial Ligands of Streptavidin (ALiS): Discovery, Characterization, and Application for Reversible Control of Intracellular Protein Transport

  摘要：

  Artificial ligands of streptavidin (ALiS) with association constants of similar to 10(6) M-1 were discovered by high-throughput screening of our chemical library, and their binding characteristics, including X-ray crystal structure of the streptavidin complex, were determined. Unlike biotin and its derivatives, ALiS exhibits fast dissociation kinetics and excellent cell permeability. The streptavidin-ALiS system provides a novel, practical compound-dependent methodology for repeated reversible cycling of protein localization between intracellular organella.
