Streptavidin

Streptavidin is a ～60 kDa homotetramer. Streptavidin binds four molecules of biotin with the highest affinity. The binding affinity of biotin to streptavidin is one of the highest reported for a non-covalent interaction to date, with a KD ～ 0.01 pM[1]. Streptavidin has an immunosuppressive role[2].
