Useful web sites


The course is divided into 3 sections.

(1) The basics of protein structure.
Using web resources to analyze the relationships between proteins.

(2) The forces that determine protein structure and function.
Hydrophobicity; Electrostatics; van der Waals interactions etc

(3) Analysis of bioenergetic proteins. These allow us to study protein function combining biochemistry, structural biology, physics, and engineering principles. We will study bioenergetic proteins that use store energy to make ATP. Some initial references here

Course Requirements. Each person will be given one protein as the basis for a ≈20 page paper. You will show your understanding of the course material in your analysis of the paper. How to write your paper.
In addition, there will be homework to be handed in most weeks. The grade will be on class participation + the paper. While the homework is pass/fail - you must hand it in at a satisfactory level to pass the class.

This class is for advanced undergraduates and graduate students. Students with diverse backgrounds in biology, chemistry, biochemistry, physics, and engineering are welcome. The fall will be mostly for students from biology and biochemistry while the spring semester is more for students with a background in the physical sciences.

Please bring to class all handouts for the section on which we are working.
