摘要：

The self-assembly of peptide nanotubes formed by an L-glutamic acid-based bolaamphiphile is shown to proceed via a remarkable mechanism where the peptide conformation changes from beta-sheet to unordered. The kinetics of this process are elucidated via X-ray scattering and UV circular dichroism methods. The reverse transition from "unordered'' to beta-sheet structures is triggered by UV radiation.
