CytochromesP-450f,P-450g,P-450h, andP-450i are four hepatic microsomal hemoproteins that have been purified from adult rats. Whereas cytochromesP-450g andP-450h appear to be male-specific hemoproteins, cytochromeP-450i is apparently a female-specific enzyme purified from untreated adult female rats. CytochromeP-450f has been purified from adult male and female rats with equivalent recoveries. Amino-terminal sequence analyses of the first 15–20 amino acid residues of each of these cytochromesP-450 has been accomplished in the current investigation. Each protein possesses a hydrophobic leader sequence consisting of 65–87% hydrophobic amino acids, and only one charged amino acid (Asp) in the ammo-terminal region. Although differences in the amino-terminal sequences of cytochromesP-450f,P-450g,P-450h, andP-450i are identified, these hemoproteins all begin with Met-Asp, and marked structural homology is observed among certain of these enzymes. CytochromesP-450g andP-450h, two male-specific proteins, have 11–12/15 identical residues with cytochromeP-450i, a female-specific isozyme. CytochromesP-450f andP-450h have 16/20 identical amino-terminal residues. Only limited sequence homology is observed between the amino-terminal sequences of cytochromesP-450f-i compared to rat liver cytochromesP-450a-e. The results demonstrate that cytochromesP-450f,P-450g,P-450h, andP-450i are isozymic to each other and five additional rat hepatic microsomal cytochromeP-450 isozymes (P-450a-e).
