Biotin streptavidin binding affinity
WebJun 14, 2007 · Korndörfer, I.P. & Skerra, A. Improved affinity of engineered streptavidin for the Strep-tag II peptide is due to a fixed open conformation of the lid-like loop at the binding site. Protein Sci ... WebSelective nitration of tyrosine residues in the four biotin-binding sites of avidin considerably reduces the affinity of the protein for biotinylated molecules above pH 9. Consequently, biotinylated probes can be adsorbed at neutral pH and released at pH ~10 (Figure 7.85). We use free biotin to block any remaining high-affinity biotin-binding sites
