Abstract
We recently reported that the bacterial 50S ribosomal protein L2 binds strongly to silica surfaces even in the presence of high salt concentrations, detergents, and denaturants such as 8 M urea. We designated L2 as Si-tag, a fusion tag for immobilizing functional proteins on silica materials. Here we discuss the remarkable properties of the Si-tag polypeptide in order to understand the mechanism underlying this binding. Experimental and...
