<tr><td class='diff-marker'>-</td><td style="background: #ffa; color:black; font-size: smaller;"><div><del style="color: red; font-weight: bold; text-decoration: none;">Streptavidin in its native form exists as a homotetramer, where adjacent subunits interact allowing for a strong interaction with biotin. This interaction is strong (Kd = 1.5E-15 M at pH 5.0) and can withstand most strong denaturing agents [1]. However when in its monomeric form, streptavidin does not maintain this strong interaction and its usefulness as a strong binder diminishes. For our system we needed a protein that could: be easily displayed on the surface of the cell, specifically bind a ligand, and release this ligand in the presence of biotin. The ability to display a protein on the cell surface is trivial, however there is difficulty in trying to get a protein to be functional on the surface of the cell. In the case of streptavidin the ability of the protein to form tetramers on the cell surface seems to be hindered, due to the poor ability of cells displaying streptavidin to bind biotinylated fluorophore (observed above). From this issue the idea of using a monomeric protein to bind biotin arose. </del></div></td><td colspan="2"> </td></tr>

However as mentioned before, as a monomer streptavidin has a weaker affinity to biotin than would be desired. Instead of screening proteins from the literature for ability to bind biotin our group approached the Baker lab at our university. After mentioning our problem, it was recommended that we design a biotin binding protein using the [http://boinc.bakerlab.org/rosetta/ Rosetta software] they developed. Rosetta in conjunction with [http://www.folt.it Fold-It] (also developed at the University of Washington) would allow use to design and optimize proteins for binding biotin. </del></div></td><td colspan="2"> </td></tr>

<tr><td class='diff-marker'>-</td><td style="background: #ffa; color:black; font-size: smaller;"><div><del style="color: red; font-weight: bold; text-decoration: none;">The first step in designing our protein was looking at the native biotin-streptavidin interaction and taking measurements between key amino acids and the biotin molecule. From here we entered the constraints into Rosetta where it matched our measurements into proteins from a protein scaffold library. This produced a large set of scaffolds with different ways each one could be used to bind biotin. These scaffolds must be screened manually, and the scaffolds that look the most promising can be placed into Fold-It. Once in Fold-It, the public has access to your protein design and can tweak and tune the protein to optimize its interaction with biotin. This allows anyone (with or without prior protein knowledge) to optimize your protein scaffold. </del></div></td><td colspan="2"> </td></tr>
