A Close Family Resemblance: The Importance of Structure in Understanding Cytochromes P450

Structure. 1998 Sep 15;6(9):1079-85. doi: 10.1016/s0969-2126(98)00109-9.

Abstract

Cytochromes P450 comprise a very large superfamily of hemeproteins which generally monooxygenate hydrophobic compounds. P450s appear to have a common conserved structural core, yet are variable in regions involved in substrate recognition and binding, and in redox-partner binding. These differences can be identified by an analysis in which structural alignments and homology models are used to compare the various classes and families of P450s.
