(a)
| 1. Make a GIF picture of the PDB file that you find in assignment 7 by RasMol. Display it in cartoon form and color it by structure. Please make the orientation of the molecule just like the molecule in the picture of assignment 7 - 2. |
|
|
| 2. Residues Glu173 and Arg177 are possible to form an ion pair (salt-bridge). (a) Draw a zoom-in picture of this pair. Show these two residues in sticks and color with cpk. The rest of protein in backbone form. (b) Measure the distance between Glu173A.OE and ARG177A.NH. |

| 3. Show a protein fragment with residues 622 to 699 only. Show them in cartoon form and color with temperature. |
|
|
| 4. Make a stereo picture for only the atoms within 6.0 Angstrom of Phe721. Show this residue in green color, others in cpk and all the residues in wireframe 0.1 format. |
