Helix Formation and Folding in an Artificial Peptide
نویسندگان
چکیده
We study the relation between α-helix formation and folding for a simple artificial peptide, Ala10Gly5-Ala10. Our data rely on multicanonical Monte Carlo simulations where the interactions among all atoms are taken into account. The free-energy landscape of the peptide is evaluated for various temperatures. Our data indicate that folding of this peptide is a two-step process: in a first step two α-helices are formed which afterwards re-arrange themselves into a U-like structure.

Effects of Dimethyl Sulfoxide and Mutations on the Folding of Abeta(25-35) Peptide: Molecular Dynamics Simulations
The 25-35 fragment of the amyloid β (Aβ) peptide is a naturally occurring proteolytic by-product of its larger parent molecule that retains the amyloid characteristics and toxicity of the full length parent molecule. Aggregation of this peptide occurs rapidly in aqueous solutions and thus characterization of its folding process is very difficult. In the present study, early stages of Aβ(25–35) ...
متن کاملFolding of a peptide corresponding to the alpha-helix in bovine pancreatic trypsin inhibitor.
A short peptide corresponding to the alpha-helical region of BPTI shows partial folding in aqueous solution (pH 7) as judged by circular dichroism (CD). Folding is temperature and denaturant sensitive, and the peptide is monomeric. The difference CD spectrum, obtained from spectra at two temperatures, indicates that the peptide folds as an alpha-helix. Difference CD spectroscopy provides a sens...
متن کاملFolding of a helix is critically stabilized by polarization of backbone hydrogen bonds: study in explicit water.
Multiple single-trajectory molecular dynamics (MD) simulation at room temperature (300 K) in explicit water was carried out to study the folding dynamics of an α-helix (PDB 2I9M ) using a polarized charge scheme that includes electronic polarization of backbone hydrogen bonds. Starting from an extended conformation, the 17-residue peptide was successfully folded into the native structure (α-hel...
متن کاملPeptide–oligonucleotide conjugates as nanoscale building blocks for assembly of an artificial three-helix protein mimic
Peptide-based structures can be designed to yield artificial proteins with specific folding patterns and functions. Template-based assembly of peptide units is one design option, but the use of two orthogonal self-assembly principles, oligonucleotide triple helix and a coiled coil protein domain formation have never been realized for de novo protein design. Here, we show the applicability of pe...
متن کاملTransformation of the mechanism of triple-helix peptide folding in the absence of a C-terminal nucleation domain and its implications for mutations in collagen disorders.
Folding abnormalities of the triple helix have been demonstrated in collagen diseases such as osteogenesis imperfecta in which the mutation leads to the substitution of a single Gly in the (Gly-X-Y)n sequence pattern by a larger residue. Model peptides can be used to clarify the details of normal collagen folding and the consequences of the interruption of that folding by a Gly substitution. NM...
