Cytochromes P450, Oxygen, and Evolution [PDF]

open access: yesThe Scientific World JOURNAL, 2001
The role of the cytochrome P450 superfamily of heme-thiolate enzymes in oxidative metabolism is discussed in the context of evolutionary development. Concordances between the rise in atmospheric oxygen content, elaboration of the P450 phylogenetic tree and the accepted timescale for the emergence of animal phyla are described. The unique ability of the
