L-alanine ethyl ester was polymerized into poly(L-alanine) (polyAla), one of the insoluble polypeptides, by papain in aqueous buffer at varying pH. At neutral pH, a maximum chain length of 11 repeats was observed. These polymers were dominated by random coiled

The journal of physical chemistry. B, 115(39), 11448-11454 (2011-08-24)
A new two-state polymer folding model is proposed, in which the folding of a stiff helical polymer is enabled by allowing for short sequences of coils connecting shorter and separated helices. The folding is driven by short-range attraction energy among

By introducing an additional hydrogen bond to hydrogen bond interaction in the force field of the CSAW (Conditioned Self-Avoiding Walk) model, we investigate into the mechanism of antiparallel β-sheet formation based on the folding of a short polyalanine in gas
Mateusz Marianski et al.
The Journal of chemical physics, 137(4), 044109-044109 (2012-08-03)
We compare the energetic and structural properties of fully optimized α-helical and antiparallel β-sheet polyalanines and the energetic differences between axial and equatorial conformations of three cyclohexane derivatives (methyl, fluoro, and chloro) as calculated using several functionals designed to treat

Biophysical journal, 102(4), 878-886 (2012-03-06)
Nested sampling is a Bayesian sampling technique developed to explore probability distributions localized in an exponentially small area of the parameter space. The algorithm provides both posterior samples and an estimate of the evidence (marginal likelihood) of the model. The
