Super-helices self-assembled from a binary system of amphiphilic polypeptide block copolymers and polypeptide homopolymers.
We report here a discovery that amphiphilic polypeptide block copolymers and polypeptide homopolymers are able to aggregate together into super-helical structures of rods and rings, in which polypeptide chains form the core and PEG chains form the shell.
متن کاملSelf-assembled templates for polypeptide synthesis.
The chemical synthesis of polypeptide chains >50 amino acids with prescribed sequences is challenging. In one approach, native chemical ligation (NCL), short, unprotected peptides are connected through peptide bonds to render proteins in water. Here we combine chemical ligation with peptide self-assembly to deliver extremely long polypeptide chains with stipulated, repeated sequences. We use a ...
متن کاملControlling Interfacial Adhesion of Self-Assembled Polypeptide Fibrils for Novel Nanoelectromechanical System (NEMS) Applications
The relative adhesion of two genetically engineered polypeptides termed as H6-(YEHK)x21-H6 and C6-(YEHK)X21-H6 has been investigated following growth and self-assembly on highly oriented pyrolytic graphite (HOPG), SiO2, Ni, and Au substrates to study covalent surface attachment via histidine (H) and cysteine (C) groups incorporated in the polypeptides. Both polypeptides formed predominantly bil...
متن کاملBiological-like vesicular structures self-assembled from DNA-block copolymers.
The polymer modification of short nucleotide sequences has been achieved for future use as self-assembled biologically active structures with sizes in the nanometre range. Co-assembly of the resulting DNA-based amphiphilic block copolymers with native proteins demonstrates the self-assembly of biological-like vesicular structures.
متن کاملLabel-free polypeptide-based enzyme detection using a graphene-nanoparticle hybrid sensor.
A graphene-nanoparticle (NP) hybrid biosensor that utilizes an electrical hysteresis change to detect the enzymatic activity and concentration of Carboxypeptidase B was developed. The results indicate that the novel graphene-NP hybrid biosensor, utilizing electrical hysteresis, has the ability to detect concentrations of targeted enzyme on the micromolar scale. Furthermore, to the knowledge of ...
