Extremely Slow Dynamics of an Abiotic Helical Assembly: Unusual Relevance to the Secondary Structure of Proteins

Abstract:
Serendipitously, we found that isoleucine methylester functionalized perylenediimide 1 undergoes an extremely slow supramolecular helical assembly over a day's time. Surprisingly, heating led to irreversible chiral denaturation. However, reversible helical assembly could be achieved only in the presence of nondenatured aggregates of 1, which act as seeds. The intriguing functional relevance deduced from 1 was employed to draw parallels with the secondary structure of proteins, envisaging its plausible implications.

Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
