Our site contains information on Cytochromes P450, Cytochromes b₅, NADPH-Cytochrome P450 reductases, β-Glucosidases, and Glycosyltransferases (Family 1). Follow any of the links above for more information, or check our recent updates.

The four structures shown above are links to the P450 (upper left), UGT (upper right), P450 reductase (lower left), and cytochrome b₅ (lower right) sections of our site. Molecular images are made using UCSF's Chimera and Adobe Photoshop.

Our last site update was on November 29, 2010

Areas Updated Recently:

• October 25, 2011 - Our P450 chapter in The Arabidopsis Book has been updated!
• November 29, 2010 - ATR3 has been putatively identified as a diflavin reductase (not a CPR). See our P450 Reductases page for more information.
• July 9, 2010 - Don't miss the 10th International Symposium on Cytochrome P450 Diversity and the 17th International Conference on Cytochrome P450 Biochemistry, Biophysics and Structure.
• November 19, 2009 - For a recent paper on plant NADPH-cytochrome P450 reductases, see Kenneth Jensen and Birger Lindberg Møller's new paper in Phytochemistry.

This site was originally hosted at the University of Arizona, based on the work for the following paper:

Intron-exon organization and phylogeny in a large superfamily, the paralogous cytochrome P450 genes of Arabidopsis thaliana.
Paquette SM, Bak S, Feyereisen R. DNA and Cell Biology (2000) 19 (5):307-17.
