The Protein Structure Prediction problem, which involves correctly predicting the geometrical conformation of a fully folded protein, is extremely difficult to solve and there currently is no “best” method of generating solutions. This paper focuses on an energy minimization technique and the use of a multiobjective genetic algorithm, the multiobjective fast messy genetic algorithm (fmGA) to ob...

the interaction between proteins and membranes has an important role in biological pro-cesses.we have calculated energies of interaction between melittin and dmpc bilayer in differenttemperatures. we have used the charmm software for md simulation under the canonical (n,v, e) ensemble at different temperatures. the computations have shown that water moleculeshave more penetration into the bilay...

Calcium ions (Ca(2+) ) play key roles in various fundamental biological processes such as cell signaling and brain function. Molecular dynamics (MD) simulations have been used to study such interactions, however, the accuracy of the Ca(2+) models provided by the standard MD force fields has not been rigorously tested. Here, we assess the performance of the Ca(2+) models from the most popular cl...

Hydration around the DNA fragment d(C5T5).(A5G5) is presented from two molecular dynamics simulations of 10 and 12 ns total simulation time. The DNA has been simulated as a flexible molecule with both the CHARMM and AMBER force fields in explicit solvent including counterions and 0.8 M additional NaCl salt. From the previous analysis of the DNA structure B-DNA conformations were found with the ...
