Figure 1From: A Viral Platform for Chemical Modification and Multivalent DisplayA view of the MS2 coat protein dimer with its two polypeptide chains shown as blue and red ribbons. The positions of amino acids altered in this study by site-directed mutagenesis are shown as yellow (glycine13), green (glycine14), magenta (threonine15), cyan (glycine113) and white (aspartic acid114). For details of the structure of MS2 coat protein see refs. 12 and 13.Back to article page
