A new aminopeptidase from diamondback moth provides evidence for a gene duplication event in Lepidoptera.

abstract：:Four cytochrome P450 genes, CYP6B8, CYP6B9, CYP6B27 and CYP6B28, exist in the Helicoverpa zea genome as two pairs of paralogs that evolved from gene duplication and 5'-polar gene conversion events. RT-PCR gel blot analyses have shown that all of these genes are expressed constitutively in midguts of all larval instars...
