Novel algorithms for searching conformational space

Abstract: The modelling of biological molecules by molecular dynamics is beset by a range of problems. The most important of these is the multiple-minima problem. The deep metastable minima can cause difficulties in proper equilibration of a molecular system and result in the simulated system being trapped in a long-lived metastable state. One way to overcome these problems is to re-engineer the 'Newtonian Rules' in order to more efficiently search conformational space. Re-engineering of the 'Newtonian Rules' implies a … Show more

“…Second, the search is easily frustrated due to the extreme ruggedness of this force field. Many algorithms have been published that tackle the problem of global energy optimization in rugged landscapes, such as Monte Carlo with minimization, [1] conformational space annealing, [2] potential-energy contour tracing, [ 3] replica exchange, [4] stochastic tunneling, [5] iterative looprelax (ILR), [6] and countless others (for two excellent reviews, see Berne and Straub [7] and Christen and van Gunsteren [8] )…”

“…Over the past several years, a multitude of conformational search methods have been devised for generating the low-energy (and hence relevant) conformers of both cyclic and acyclic molecules, and the practicing computational chemist can now choose from a wide variety of procedures for conformational searching the stochastic (sometimes referred to as Monte Carlo) variation of torsion angles (including methods that rely on the genetic algorithm ), methods based on Metropolis Monte Carlo , (including simulated annealing ), the stochastic variation of Cartesian coordinates, the stochastic variation of internuclear distances (distance geometry), methods that employ molecular dynamics, , and the flapping, , flipping, or flexing of rings or mapping of rings onto generic shapes …”
