Abstact

Artificial ligands of streptavidin (ALiS) with association constants of ∼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.
