Methods for high-throughput synthesis and screening of peptide libraries

Macrocycles provide an attractive modality for drug development but the identification of ligands to targets of interest is hindered by the lack of large macrocyclic compound libraries for high-throughput screening. A strategy to efficiently synthesize lar ...

Single-Molecule Peptide Identification Using Fluorescence Blinking Fingerprints

Pablo Rivera Fuentes, Salome Riccarda Püntener

The ability to identify peptides with single-molecule sensitivity would lead to next-generation proteomics methods for basic research and clinical applications. Existing single-molecule peptide sequencing methods can read some amino acid sequences, but the ...

Synthesis and application of bifunctional hypervalent iodine reagents for peptide modification.

Elija Grinhagena

Protein-protein interactions (PPIs) are responsible for regulating many biological processes in human bodies. PPIs often have a large binding site and often interact through an alpha helical segment. Therefore, the inhibition of PPIs can be difficult using ...

Competing Effects of Hydration and Cation Complexation in Single-Chain Alginate

Alginic acid, a naturally occurring anionic polyelectrolyte, forms strong physically cross-linked hydrogels in the presence of metal cations. The latter engage in electrostatic interactions that compete with intra- and intermolecular hydrogen bonds, determ ...

Solid-phase peptide synthesis on disulfide-linker resin followed by reductive release affords pure thiol-functionalized peptides

Christian Heinis, Peter Matei Frisius Pânzar, Alexander Lund Nielsen, Manuel Leonardo Merz, Ganesh Kumar Mothukuri, Zsolt Bognár

Thiol groups are suitable handles for site-selectively modifying, immobilizing or cyclizing individual peptides or entire peptide libraries. A limiting step in producing the thiol-functionalized peptides is the chromatographic purification, which is partic ...

Hypervalent Iodine-Mediated Late-Stage Peptide and Protein Functionalization

Jérôme Waser, Elija Grinhagena, Emmanuelle Madeline Dominique Allouche

Hypervalent iodine compounds are powerful reagents for the development of novel transformations. As they exhibit low toxicity, high functional group tolerance, and stability in biocompatible media, they have been used for the functionalization of biomolecu ...

A minimalistic cyclic ice-binding peptide from phage display

Harm-Anton Klok, Luciano Andres Abriata, Corey Alfred Stevens, Matthew Gibson, Xudong Kong

Developing molecules that emulate the properties of naturally occurring ice-binding proteins (IBPs) is a daunting challenge. Rather than relying on the (limited) existing structure–property relationships that have been established for IBPs, here we report ...

Molecular basis for inhibition of adhesin-mediated bacterial-host interactions through a peptide-binding domain

Corey Alfred Stevens

Infections typically begin with pathogens adhering to host cells. For bacteria, this adhesion can occur through specific ligand-binding domains. We identify a 20-kDa peptide-binding domain (PBD) in a 1.5-MDa RTX adhesin of a Gram-negative marine bacterium ...

The Drosophila Baramicin polypeptide gene protects against fungal infection

Bruno Lemaitre, Mark Austin Hanson, Igor Iatsenko, Alice Marra

The fruit fly Drosophila melanogaster combats microbial infection by producing a battery of effector peptides that are secreted into the haemolymph. Technical difficulties prevented the investigation of these short effector genes until the recent advent of ...

KAT Ligation for Rapid and Facile Covalent Attachment of Biomolecules to Surfaces

Nako Nakatsuka, Nicholas Spencer

The efficient and bioorthogonal chemical ligation reaction between potassium acyltrifluoroborates (KATs) and hydroxylamines (HAs) was used for the surface functionalization of a self-assembled monolayer (SAM) with biomolecules. An alkane thioether molecule ...
