Abstract: The conformational analysis of spider dragline silks is difficult because of the amorphous character of the silks. In this article, the fractions of several conformations were determined for three 47-mer peptides, (Glu)4(Ala)6GlyGly12Ala13Gly14GlnGlyGlyTyrGlyGlyLeuGlySerGlnGly25Ala26Gly27-ArgGlyGlyLeuGlyGlyGlnGly35Ala36Gly37(Ala)6(Glu)4, with three underlined… read more here.
