Inducible P450s of the CYP9 family from larval Manduca sexta midgut.

Abstract

Several related cytochrome P450 cDNAs belonging to the CYP9 family have been cloned from the midgut of larval tobacco hornworms, Manduca sexta. The first P450, CYP9A2, was obtained by RT-PCR using degenerate primers. Northern blot analysis of expression in the midgut using the CYP9A2 probe revealed a significant induction by a variety of chemicals. Diets… (More)
