Part 02

Chapter 04 - The structure of proteins

A useful site giving an overview of protein structure can be found here:
http://lectures.molgen.mpg.de/ProteinStructure/index.html

If you want to look up the structure of a protein, you can visit the Protein Data Bank and either search on a protein name, or enter the protein data bank (PDB) code if you know it:
http://www.rcsb.org/pdb/home/home.do

Chapter 05 - Methods in protein investigation

This is a site describing the use of x-ray crystallography in the study of proteins:
http://www-structmed.cimr.cam.ac.uk/Course/Overview/Overview.html

This site features explanations of several key biophysical techniques, which can be applied to the study of proteins:

Chapter 06 - Enzymes

This very useful site from the University of Arizona has a range of problem sets as well as having descriptive material:
www.biology.arizona.edu/biochemistry/problem_sets/en ergy_enzymes_catalysis/energy_enzymes_catalysis.html

A second site, with relatively simple material, is:

Chapter 07 - The cell membrane and membrane proteins

The University of Arizona site has a tutorial and problems suitable for this chapter at:
www.biology.arizona.edu/cell_bio/problem_sets/membranes/index.html

There is a quiz and a guide to membrane characteristics at:
http://library.thinkquest.org/27819/ch3_1.shtml

A nice site for learning about the structure and construction of the cell membrane can be found here:

Chapter 08 - Muscle contraction, the cytoskeleton and molecular motors

There is a series of lectures in interactive format on muscle at:
www.uic.edu/classes/phyb/phyb516

Information on the cytoskeleton at:
http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/C/Cytoskeleton.html

A cytoskeleton tutorial at:
www.biology.arizona.edu/cell_bio/tutorials/cytoskeleton/main.html

Coverage of molecular motors in Alberts et al, Molecular Biology of the Cell, can be found here:
