DOI: 10.1002/1873-3468.14216
Abstract: Although the effect of thermal perturbations on protein structure has long been modelled in helical peptides, several details, such as the relation between the thermal stabilities of the propagating and nucleating segments of helices, remain elusive. We had… read more here.

DOI: 10.1002/bip.23575
Abstract: Conformational search and density functional theory calculations were performed to explore the preferences of helical structures for chiro‐specific oligo‐γ‐peptides of 2‐(aminomethyl)cyclopentanecarboxylic acid (γAmc5) with a cyclopentyl constraint on the Cα–Cβ bond in solution. The dimer… read more here.

DOI: 10.1002/cbic.202400427
Abstract: While foldamers have been extensively studied as protein mimics and especially as α‐helix mimics, their use as capping motif to enhance α‐helix propensity remains comparatively much limited. In this study, we leverage the structural similarities… read more here.

DOI: 10.1002/chir.23416
Abstract: We report the first example of solvent-dependent helix inversion in poly(diphenylacetylene) (PDPA) derivatives. Asymmetrically substituted PDPAs bearing optically active substituents linked through amide bonds formed preferred-handed helical conformations because of the optically active substituents in… read more here.

DOI: 10.1002/jcb.30369
Abstract: Specific interactions between transcription factors (TFs) and substrate DNA constitute the fundamental basis of gene expression. Unlike in TFs like basic helix‐loop‐helix or basic leucine zippers, prediction of substrate DNA is extremely challenging for helix‐turn‐helix… read more here.
