## Abstract

A cytochrome P-450e gene variant has been isolated from the rat liver genomic library. It is a typical e gene clone but unique in having b-like single base substitutions at specific sites in the $5^{\prime}$ flanking region. It also appears to have certain additional restriction sites in the introns. When compared with the cytochrome P-450b gene, the e gene has some of the repetitive motifs interrupted in the $5^{\prime}$ flanking region. In addition, this region is characterized by the presence of alternating pyrimidine-purine stretch, steroid hormone regulatory elements, consensus eukaryotic enhancer sequence and sequences involved in general amino acid regulation.
