The binding model, suggested by Brian Matthews, is shown schematically in (a) with connected circles for the Ca positions, (b) A schematic diagram of the Cro dimer with different colors for the two subunits, (c) A schematic space-filling model of the dimer of Cro bound to a bent B-DNA molecule. The sugar-phosphate backbone of DNA is orange, and the bases ate yellow. Protein atoms are colored red, blue, green, and white, [(a) Adapted from D. Ohlendorf et al., /. Mol. Evol. 19 109-114, 1983.

Table 1 Relative energies per atom of several structures for each of the metals examined by the tight-binding model discussed in the text. The energy of the experimental ground state structure is arbitrarily set to zero. All energies are calculated at the equihbrium volume found by the tight-binding fit, and are expressed in mRy. Below the common name of eacli phase is its Struldtirberirht designation.

Figure 10.8 Three-point binding model for prediction of NeuA stereoselectivity based on conformational analysis.

These CD studies confirmed the binding stoichiometries of our aPNA-DNA complexes and provided further support for our binding model. Comparisons between the CD spectra of the individual components and the aPNA DNA complex suggest a template effect (not unhke that observed with certain DNA-binding proteins) where the components induce mutual conformational changes upon their interaction with each other.

By combining the results of the Newns-Andersons model and the considerations from the tight binding model it is now possible to explain a number of trends in surface reactivity. This has been done extensively by Norskov and coworkers and for a thorough review of this work we refer to B. Hammer and J.K. Norskov, Adv. Catal. 45 (2000) 71. We will discuss the adsorption of atoms and molecules in separate sections.

As all of the data are collected and analyzed it is also important to start considering a binding model or pharmacophore model to help explain the variation in biological activity with structure, and to provide a basis for the design of new analogs.
