Abstract:
:The design of dimeric coiled-coils has ultimately led to novel applications, such as self-replicating peptide systems, whereas the structural features of the less common trimeric coiled-coil continue to be elucidated. Novel topologies have been discovered in designed proteins, as exemplified by the right-handed tetrameric coiled-coil and the inverted U four-helix bundle, and a single switch of two amino acids within a protein has been shown to be sufficient to designate a new protein fold. Conformational switching from helix to sheet has been observed for designed peptides and transcription factors, whereas peptides designed from beta-amino acids have been found to adopt a helical conformation in aqueous solution.
