Biochem/physiol Actions
L-Alanine has wide range of applications as food additive and as a component in infusion solutions. It is also used as a precursor for chemical and pharmaceutical products. In a penta-alanine system, resampling helps to increase the efficacy of a “fast-switch” equilibrium sampling protocol.

Terahertz time domain spectroscopy shows that the protein dynamical transition, the rapid increase in protein dynamics occurring at approximately 200 K, needs neither tertiary nor secondary structure. Further, short chain alanine studies find a dynamical transition down to penta-alanine, with

We recently applied a multistage reweighting scheme to demonstrate the sampling of equilibrium configurational distributions of peptides from nonequilibrium, simulated annealing trajectories [E. Lyman and D. M. Zuckerman, J. Chem. Phys. 127, 065101 (2007)]. Here we demonstrate that a statistical
