Web3 sep. 2003 · Although a β-hairpin has larger potential energy than an α-helix, the entropy of a β-hairpin is larger because of fewer constraints imposed by the hydrogen bonds. In the vicinity of the transition temperature, we observe the interconversion of the α-helix and β-sheet states via a random coil state. WebRv2466c is a homodimer in which each subunit displays a modular architecture comprising a canonical thioredoxin-fold with a Cys(19)-Pro(20)-Trp(21)-Cys(22) motif, and an insertion consisting of a four α-helical bundle and a short α-helical hairpin.
