Links to Information about Enzymes:

Great Enzyme info (from PowerPoint) - This site provides all the necessary information covered in this lab.  This can be a nice reference for your lab report.  Make sure to paraphrase and cite this info!

Proteins denatured when Frying an egg!

Proteins as catalysts from Molecular Biology of the Cell (highly respected cell biology textbook).  This chapter is a good introduction to catalysis.  However, it is written for junior-senior level courses, so its best to have read about enzymes in our text (Campbell) first.

Paustian, Timothy.  2000.  Enzymes- The Biological catalysts.  This page includes good animations of a chemical reaction (Figures 2,3,4).  The two substrates (triangle and hexagon, Figure 2) must contact each other in a precise orientation to combine (Figure 3).  The enzyme active site binds both substrates in a favorable position to react (Figure 4).  After they react, they no longer stick to the active site, freeing it to catalyze again.  The reaction speeds up because both substrates are likely to stick to the active site. 

The Biology Project: Energy, enzymes and catalysis problem set. at U of Arizona. Multiple choice questions and brief tutorials about biology fundamentals.  The tutorials come up if you answer incorrectly- so its useful to be wrong!  This page is a small part of an extensive site.

Molecular Modeling Database at NCBI (National Center for Biotechnology Information) contains over 10,000 structures 3-D macromolecular structures, including proteins and polynucleotides (DNA & RNA).   Find a 3-D structural diagram of galactosidase, the enzyme we are working with.  An application called Cn3D must be loaded to view the structures.  You can download the Cn3D viewer.  The NCBI site is also a major repository of genetic information for researchers.
