This image is a phylogenetic tree of 43 sequences.

They are single members of subfamilies from the top half of the P450 tree.

The sequences are from top to bottom: 2C9, 2H1, 2E1, 2F1, 2G1rat, 2A6, 2Q1

2B6, 2M1, 2N1, 2P1, 2J1, 2D6, 2K1, 2L1, 18, 1A1trout, 1A1human1, 1A2chick,

Note: The last five sequences naturally fall in the lowerhalf of the tree.

They are included here, because they are plant sequences. See the single

family member tree for a more accurate placement of these sequences.
