Research Abstract

The silica-binding protein "Si-tag" belongs to a family of intrinsically disordered (ID) proteins that exist as dynamic ensembles of rapidly fluctuating structures in aqueous solution. Experimental and theoretical studies have shown that the ID regions in Si-tag act in unison to bind strongly to silica surfaces. Si-tag should interact with a large area of the silica surface due to the relatively large number of residues in its extended, disordered regions. Our study suggests that flexible ID proteins have tremendous potential for connecting biomolecules to inorganic materials.
