BETA STRUCTURE - SADDLES AND BARREL

an example for your student projects

Look at this page using your browser and Microsoft Front Page Editor (including the HTML code) to get an ideal of some of the things you can for your project. Through this site, you can view images of beta structure. The first image in the molecule frame above is that of a beta-saddle from arabinose binding protein. It was modified by the molecular editor of Q/C to show only the beta-saddle. Manipulate it with the mouse commands.    

Mouse Commands

Use the left mouse button to manipulate the screen

The right frame - commands.html - gives a list of commands which will alter the display of the structure and properties of the molecule.   Click on the different command buttons and  watch the changes!

The bottom frame - page1.html - displays the text associated with each molecule displayed in the top frame.  The text in this frame will describe the structure and function of the displayed molecule, and prompt you to change the view of the molecule by selecting different commands in the right frame.

You should describe the twisted beta sheet by addition of the appropriate text here. You can add commands that alter the rendering of the molecules that parallel your textual comments. Commands for starting and stopping the rotation of the molecule are placed below just as examples.

Now check out another view of beta structure, a beta barrel from triose phosphate isomerase. (In your own presentation you would probably load a PDB file showing a blowup of the active site or binding site that you made using Quanta/Charmm as described in the instructions.html file. ) as a: 

Load a beta-barrel.

This is a beta barrel from TIM made with Q/C.... Here you add more text describing the new file. You can add commands that alter the rendering of the molecules. Commands for starting and stopping the rotation of the molecule are placed below just as examples.

Continue adding text comments and appropriate buttons to change the rendering. As described in the instruction.html file, not all changes have buttoms which can be inserted in the page1.html file. In some case, just add textual comments prompting the reader to right click on the molecule and alter rendering in that fashion, as described in the instruction file.
