A Amino acid sequence of GPG. B Temperature-dependent CD spectra of the GPG. C AFM images of the assembled structures of GPG formed at 45 °C. (i) Particles formed just after preparation; (ii) particles and (iii) nanofibers formed on Day 1 at different locations on the mica substrate; (iv) nanofibers formed on Day 2 and (v) Day 7; (vi) high-magnification image of nanofibers with a beaded structure on Day 7. D, E CD spectra and AFM or transmission electron microscopy (TEM) images of the assembled structures formed on Day 7 for the proline-rich monoblock (D), glycine-rich monoblock (E), and diblock (F) polypeptides. G Tentative model for the assembly of GPG into nanofibers. Adapted with permission from ref. [22] Copyright 2013, American Chemical Society
