David Nelson's homepage:David Nelson keeps an update of P450 sequences characterized in all organisms and is also the'P450 nomenclature committee', the person to contact to obtain a name for a new P450 sequence. Nelson also provides a simple introductory lecture on mammalian P450 enzymes and on all their hysiological and other functions.

Home Page of the Human Cytochrome P450 (CYP):Allele Nomenclature Committee An update of the knowledge on allelic variants of
the human genes; also provides instructions on the submission of new variants.

Directory of P450-containing systems:Lists P450 and related genes. More information on P450 structure, ligands, domain structure,electron donors and useful links on human alleles,drug metabolism, commercially available forms;also contains references.
