Molecular processes depending on protein–protein interactions can use consensus recognition sequences that possess defined secondary structures. Left‐handed polyproline II (PPII) helices are a class of secondary structure commonly involved with cellular signal transduction. However, unlike...
Peptide C‐terminal N‐alkyl amides have gained more attention over the past decade due to their biological properties, including improved pharmacokinetic and pharmacodynamic profiles. However, the synthesis of this type of peptide on solid phase by current available methods can be challenging....
Silkmoth chorion is the major component of the silkmoth eggshell. The proteins that constitute more than 95% of its dry mass have remarkable mechanical and physicochemical properties forming a protective natural shield for the oocyte and the developing embryo from a wide range of environmental...
The hydrogels assembled from a pair of self‐repulsive but mutually attractive decapeptides are visualized by magnetic resonance imaging (MRI). It is found that in the absence of Gd(III)‐chelate, gelation has little effect on MRI signal intensity. In the presence of Gd(III)‐chelate, gelation...
Developing efficient cellular delivery vectors is crucial for designing novel therapeutic agents to enhance their plasma membrane permeability and metabolic stability in cells. Previously, we engineered cell penetrating peptide vectors named as “lipo‐oligoarginine peptides” (LOAPs) by...
The Aib‐DAla dipeptide segment has a tendency to form both type‐I′/III′ and type‐I/III β‐turns. The occurrence of prime turns facilitates the formation of β‐hairpin conformations, while type‐I/III turns can nucleate helix formation. The octapeptide...
Structural characterization of G protein‐coupled receptors (GPCRs) is hindered by the inherent hydrophobicity, flexibility, and large size of these signaling proteins. Insights into conformational preferences and the three‐dimensional (3D) structure of domains of these receptors can be...
