    Abstract

    Hypertrehalosemic hormone (a carbohydrate-mobilizing neuroendocrine decapeptide) and starvation markedly increased levels of a cockroach (Blaberus discoidalis) fat body cytochrome P450 message. The gene represented by the cloned P450 cDNA has been named CYP4C1 (cytochrome P450 family 4, subfamily C, gene 1), a newly identified member of the ubiquitous cytochrome P450 monooxygenase gene superfamily. Blaberus CYP4C1 (511 amino acids, Mr = 58,485) has a hydrophobic NH2 terminus and a sequence near the COOH terminus that is homologous to the cysteine-containing heme-binding region definitive of cytochromes P450. The cockroach sequence is 32-36% identical to mammalian family 4A and 4B enzymes. It contains a 13-residue sequence characteristic of family 4 but not other P450s. This study suggests that CYP4C1 is hormonally regulated in association with energy substrate mobilization and supports the idea that family 4 is an old and widespread gene family.
