Background
Streptavidin is a 52.8 kDa protein from the bacterium Streptomyces avidinii. Streptavidin is a homo-tetramer forming a beta-barrel with an extraordinarily high affinity for biotin (also known as vitamin B7). It has a dissociation constant (K
d) on the order of ≈10
−14 mol/L.
The binding of biotin to streptavidin is one of the strongest
non-covalent interactions known in nature and has a high resistance to organic solvents,
denaturants, detergents, proteolytic enzymes, and extreme pH ranges or temperatures.
Limitations
