"Animals often have more CYP genes than do humans. Reported numbers range from 35 genes in the sponge Amphimedon queenslandica to 235 genes in the cephalochordate Branchiostoma floridae. Mice have genes for 101 CYPs, and sea urchins have even more (perhaps as many as 120 genes). Most CYP enzymes are presumed to have monooxygenase activity, as is the case for most mammalian CYPs that have been investigated (except for, e.g., CYP19 and CYP5).
