Engineered single-chain dimeric streptavidins with an unexpected strong preference for biotin-4-fluorescein

Streptavidin, a homotetrameric protein with extremely tight biotin binding (K(d) ≤ 10(-14) M), has been widely used as an affinity reagent. Its utility would be increased by engineering single-chain mutants with a wide spectrum of affinities, more suitable for phage-display and chip technologies. By...
