Figure 3.6 Four-helix bundles frequently occur as domains in a proteins. The arrangement of the a helices is such that adjacent helices in the amino acid sequence are also adjacent in the three-dimensional structure. Some side chains from all four helices are buried in the middle of the bundle, where they form a hydrophobic core, (a) Schematic representation of the path of the polypeptide chain in a four-helrx-bundle domain. Red cylinders are a helices, (b) Schematic view of a projection down the bundle axis. Large circles represent the main chain of the a helices small circles are side chains. Green circles are the buried hydrophobic side chains red circles are side chains that are exposed on the surface of the bundle, which are mainly hydrophilic.

At the end of the 2D experiment, we will have acquired a set of N FIDs composed of quadrature data points, with N /2 points from channel A and points from channel B, acquired with sequential (alternate) sampling. How the data are processed is critical for a successful outcome. The data processing involves (a) dc (direct current) correction (performed automatically by the instrument software), (b) apodization (window multiplication) of the <2 time-domain data, (c) Fourier transformation and phase correction, (d) window multiplication of the t domain data and phase correction (unless it is a magnitude or a power-mode spectrum, in which case phase correction is not required), (e) complex Fourier transformation in Fu (f) coaddition of real and imaginary data (if phase-sensitive representation is required) to give a magnitude (M) or a power-mode (P) spectrum. Additional steps may be tilting, symmetrization, and calculation of projections. A schematic representation of the steps involved is presented in Fig. 3.5. [Pg.163]

As in previous chapters, the reader will find below for a number of structures a schematic representation, generally through a number of sections and/or projections of the unit cells, often together with a few adjacent cells. As an exercise and an introduction to the subsequent descriptive paragraphs, a few examples with indications about their interpretation are given here. [Pg.623]

Figure 35 presents the motions of C02s and radicals in the pathway containing A13 through a schematic representation which is consistent with the IR and EPR observations. The view shows projections of fragments on the plane parallel to the a axis and 40.3° from the b axis of the crystal. The crystallographic a axis is vertical, so that this view is equivalent to the one shown in Figure 9. Unresolved ambiguities regarding position and orientation of the C02s are discussed below.
