Molecular mechanics background

A comprehensive and up-to-date introduction to the ideas of molecular dynamics and Monte Carlo, with statistical mechanical background, advanced teclmiques and case studies, supported by a Web page for software download. 

This text is similar to that of McCammon and Harvey (see below), but also provides a background for force field-based calculations and a more sophisticated discussion. Includes numerous examples of computing the structure, dynamics, and thermodynamics of proteins. The authors provide an interesting chapter on the complementary nature of molecular mechanics calculations and specific experimental techniques. 

The background theory that underlies the FEP method as well as the molecular mechanics force fields that relate molecular structure to energy are reviewed in section one of the book. Section two describes the use of free energy calculations for determining molecular properties of ligands, including solvation, as calculated using both implicit and explicit water... 

A good, brief introduction to the simple Hiickel method is Roberts JD (1962) Notes on molecular orbital calculations. Benjamin, New York, pp 87-90. A detailed treatment Streitweiser A (1961) Molecular orbital theory for organic chemists. Wiley, New York, pp. 380-391 and references therein.

This presentation is structured in the following way. The first section outlines the procedure for the quantum mechanics and classical mechanics approach. The following two sections contain an overview of how to establish a density functional theory and molecular mechanics method along with the theoretical background for... 

This section contains the background for the combination of density functional theory and molecular mechanics. Following the basic philosophy of quantum mechan-ics/molecular mechanics approaches we partition the total system into at least two parts which can be treated simultaneously. The quantum mechanical subsystem is described using DFT and the classical subsystem is given by molecular mechanics. Based on the QM/MM approach we have that the total energy of the system is... 

The field of inorganic molecular modeling has developed in the past five years to an extent that it has led us to add some chapters and rewrite others. The division of the book into three parts I Theory, II Applications and III Practice that can be read and used separately is retained. Our emphasis is still on empirical force field calculations. Quantum-mechanical calculations have undergone an enormous development in recent years, and techniques such as DFT and combined quantum mechanics/molecular mechanics (QM/MM) are now routinely used by theoreticians and experimentalists to predict and interpret structures, stabilities, electronic properties and reactivities of metal-containing compounds. Where appropriate, we have included results derived from such methods in this second edition of our book, without going into detailed discussion of the theoretical background, since this is given in many recent textbooks and review articles. 

There is no high-resolution three-dimensional structure available for any of the mammalian ABC transporters, thus the structural background of the MDR molecular mechanism is currently unresolved. A low-resolution structure of the MDR1 [37] indicates that the protein is embedded into the membrane as a cylinder with a large central pore, which is closed at the inner (cytoplasmic) face of the membrane. This structure also included an opening of this cylinder to the lipid phase. 

The present contribution concerns an outline of the response tlieory for the multiconfigurational self-consistent field electronic structure method coupled to molecular mechanics force fields and it gives an overview of the theoretical developments presented in the work by Poulsen et al. [7, 8, 9], The multiconfigurational self-consistent field molecular mechanics (MCSCF/MM) response method has been developed to include third order molecular properties [7, 8, 9], This contribution contains a section that describes the establisment of the energy functional for the situation where a multiconfigurational self-consistent field electronic structure method is coupled to a classical molecular mechanics field. The second section provides the necessary background for forming the fundamental equations within response theory. The third and fourth sections present the linear and quadratic, respectively, response equations for the MCSCF/MM response method. The fifth 283... 

In addition to blocatalytlc, energy-transducing and Information transducing membranes, there are, of course, other types of blofunctlonal synthetic membranes. However, this review concentrates on these three Important blofunctlonal membranes. The historical background of their development, the molecular mechanism In biological membranes on which blofunctlonal synthetic membranes are modelled, the methodology of membrane preparation and current trends In the research and development are described.
