GRASP program

The groove that extends down from it is highly hydrophobic and was initially assumed to be the inhibitor binding site. Figure prepared using the GRASP program [49]. 

Figure 7 MEP maps on the van der Waals envelope of the active site emerging from itself (left) and from the surrounding protein (right), (a) Trypsin, (b) xylose isomerase. Red negative, blue positive MEP values. Figure by Ms. T. G6rczei (Budapest) using the GRASP program ...

Conclusions from the test problems are not limited by any means to methanol synthesis. These results have more general meaning. Other reactions also will be used to explain certain features of the subjects. Yet the programs for the test problem make it possible to simulate experiments on a computer. In turn, computer simulation of experiments by the reader makes the understanding of the experimental concepts in this book more profound and at the same time easier to grasp.

The open end of IL-1(3, shown as a surface. The positions of some of the residues that have been subjected to site-directed mutagenesis studies have been marked. Produced using the program GRASP [108]. 

TJtiis list applies to the whole program but at the beginning of each section you will find a list of "concepts assumed". This will be a more detailed analysis of the concepts I expect you to have grasped before you start that section. You will find help in the textbooks or from your adviser if you are unsure of any of these concepts. 

Fig. 4. Computer graphics of the domain interface building the channel to the active center in PDC. The thiazolium ring of ThDP is visible at the bottom of the channel. A tryptophane residue (blue) has been engineered into the crystal structure of PDCS.u. by means of computer graphics. The picture was generated by J. Grotzinger using the program GRASP [181]...

Using the program GRASP (Nicholls ei al.. 1991). accessible surface area calculations based on the Shrake Rupley (1973) Hydrogen bonds in domain interfaces, with water-mediated hydrogen bonds in parentheses. 

The illustration program is a key component of the visual emphasis in Organic Chemistry. Besides traditional skeletal (line) structures and condensed formulas, there are numerous ball-and-stick molecular models and electrostatic potential maps to help students grasp the three-dimensional structure of molecules (including stereochemistry) and to better understand the distribution of electronic change. 

Adapt the educational program to the child s cognitive level and stage of development. Education should be based on the child s maturity and ability to grasp...
