a Schematic illustration of full-length major ampullate spidroins, including: N-terminal domain (NT), repetitive central region (poly-Ala/Gly), and C-terminal domain (CT). b The comparative modeling (homology model) of CT domain of E. australis MaSp186, shown with chain A in blue, chain B in orange and the inter-chain disulfide bridge represented in yellow. The amino acid residues forming salt bridges are visualized with stick representation where the negative charges are red and the positive charges are blue. c CD spectroscopy of CT domain (MaSp1 E. australis) at pH 8 presents the canonical α-helix pattern with minima at 222 nm and 208 nm. d The sequence of CT with the α-helices indicated, and the conservation score according to ConSurf 83. The images were rendered using Pymol.
