Neighbor-join tree of representative P450 protein sequences. Organisms are
abbreviated as shown below. Branches and labels are color-coded according
to phylogenetic classification. Mammals: red; other vertebrates: dark
brown; insects: brown; other invertebrates light brown; nematodes: orange;
plants: green; fungi: dark blue; protist: dark green; prokaryotes: magenta.
The P450 superfamily members are divided into two classes (E- and
B-classes).  The E-class members are further classified into six major
groups (I-VI) indicated by Roman numbers. This tree was presented at the
Fifth International Symposium on P450 Biodiversity, July 2-6, 2000,
Elsinore, Denmark.
