Question

Using the PDB and pymol answer the following questions about the Hexokinase structure with the PDB cose 4QS7:

1. How many polypeptide chains are in this structure?

2. There are two beta sheets in the structure. Are they...

parallel

antiparallel

both

neither

3. Visualize (show in the structure) the glucose molecule, and amino acids T194, N229, N256, and E315. What do these residues appear to be doing? It may help if you: select the glucose, click A(ction) for the selection -> find -> polar contacts -> to other atoms in object.

4. Rotate around the structure so that you can see all of the polypeptide along with the glucose and amino acids you visualized in question 9. Make sure the amino acids are clearly visible, but you do not need to label them.
