Background：
Streptavidin is a tetrameric protein expressed in Streptomyces avidinii. Because of its high affinity for the vitamin h-biotin, Streptavidin is commonly used in the fields of molecular biology and biotechnology. The Strep-tag was originally selected from a genetic library to specifically bind to a proteolytically truncated "core" version of streptavidin. Over the years, the Strep-tag was systemically optimized, to permit a greater flexibility in the choice of attachment site. Further, its interaction partner, Streptavidin was also optimized to increase peptide-binding capacity, which resulted in the development of Strep-Tactin. The so called Strep-tag system, consisting of Strep-tag and Strep-Tactin, has proven particularly useful for the functional isolation and analysis of protein complexes in proteome research.
