This book provides very good coverage of the computational techniques used in the study and modeling of biomolecules. The book consists of 16 chapters covering such topics as the application of hybrid quantum mechanical/molecular mechanical potentials for the description of enzyme systems, ab initio studies on nucleic acid bases and the radiation damage to DNA, protein structure prediction, and drug design strategies.

Using results from ab initio studies, the author details proton-transfer properties by way of single- well and double-well potentials and discusses hydrogen bond flexibility and different types of hydrogen bonds (LBHB, SSHB, etc.).

In Chapter 3, S ˇ poner, Hobza, and Leszczynski present a detailed overview of ab initio studies on nucleic acid bases, covering the choice of basis sets and the importance of basis set superposition error (BSSE) and describing the geometric features of the base pairs. Chapters 4 (M. Orozco et al.) and 5 (L. Gorb and J. Leszczynski) offer insights into the effects of solvation on the geometries of nucleic acid base pairs and various theoretical treatments for the inclusion of solvation effects. In Chapter 6 (M. Aida, M. Kaneko, and M. Dupuis), pyrimidine dimers are studied using ab initio methods to obtain a detailed understanding of the radiation-induced damage to DNA. Radiation-induced damage to DNA is also investigated in Chapter 7 (A.-O. Colson and M. D. Sevilla) through molecular orbital studies on DNA base radicals. Using molecular dynamics simulation studies, Bansal, Ravikiran, and Chowdhury present a detailed description of the geometric features in guanine-rich helical structures (Chapter 8).

Chapters 11-14 discuss the use of various computational approaches for protein structure prediction, for modeling DNA-protein interactions, and for studies on small-molecule and peptide interactions with membranes.

The bookconsists of 16 chapters covering such topics as the application of hybridquantum mechanical/molecular mechanical potentials for the descriptionof enzyme systems,ab initio studies on nucleic acid bases and theradiation damage to DNA, protein structure prediction, and drug designstrategies.
