WebA nuclear heme pool appears to regulate the transcription of the cytochrome P450 2B1/2B2 genes in rat liver, by modulating binding of a transcription factor (s) that appears to be involved in the transcriptional activation by phenobarbitone. Publication types Review MeSH terms Animals Cytochrome P-450 Enzyme System / metabolism* WebThe cytochrome P450 superfamily is a highly diversified set of heme containing proteins. These proteins were discovered in 1958 by their unusual reduced carbon monoxide difference spectrum that has an absorbance at 450 nm, thus Pigment at 450 nm or P450. This odd spectrum is caused by a thiolate anion acting as the 5th ligand to the the heme.
