Control of Peptide Secondary Structure and Dynamics in Poly(γ-benzyl-L-glutamate)-b-polyalanine Peptides
The stability, persistence and dynamics of the peptide secondary motifs are investigated in a series of poly(γ-benzyl-L-glutamate)-b-polyalanine (PBLG-b-PAla) polypeptides through a combination of structural (X-rays, NMR) and dynamic (Dielectric Spectroscopy, NMR) probes. The unfavorable enthalpic interactions between the unlike blocks give rise to nanophase separation that results in the desta...
متن کاملElucidation of the structure of poly(γ-benzyl-l-glutamate) nanofibers and gel networks in a helicogenic solvent
The synthesis, characterization, self-assembly, and gel formation of poly(γ-benzyl-l-glutamate) (PBLG) in a molecular weight range from ca. 7,000-100,000 g/mol and with narrow molecular weight distribution are described. The PBLG is synthesized by the nickel-mediated ring-opening polymerization and is characterized by size-exclusion chromatography coupled with multiple-angle laser light scatter...
متن کاملPegylation of poly(γ-benzyl-L-glutamate) nanoparticles is efficient for avoiding mononuclear phagocyte system capture in rats
Poly(γ-benzyl-L-glutamate) (PBLG) derivatives are synthetic polypeptides for preparing nanoparticles with well controlled surface properties. The aim of this paper was to investigate the biodistribution of pegylated PBLG in rats. For this purpose, nanoparticles were prepared by a nanoprecipitation method using mixtures of different PBLG derivates, including a pegylated derivate to avoid mononuc...
متن کاملTactoidal shell defects in poly (γ-benzyl-D-glutamate) liquid crystals
2014 Under certain conditions, tactoidal shell defects (TSD’s) can be produced in magnetically oriented samples of poly (03B3-benzyl-D-glutamate) liquid crystals. Their shape is reminiscent of liquid crystalline droplets or tactoids found in various biphasic colloidal systems and solutions of plant viruses. In contrast to tactoids, however, TSD’s form a boundary surface which separates two regi...
متن کاملHelix–coil transformation of poly(c-benzyl-L-glutamate) with polystyrene attached to the N or C terminus in trifluoroacetic acid–chloroform mixtures
The helix–coil transformations of block copolymers composed of poly(c-benzyl-L-glutamate) (PBLG) and polystyrene (PS), in which PS was attached to either the N terminus (PBLGn-N-PSm) or the C terminus (PSn-C-PBLGm) of PBLG, were investigated in trifluoroacetic acid (TFA)–chloroform mixtures with TFA concentrations in the range of 0.7–10 vol%. The helical content (fH) estimated from 1H nuclear m...
