Based on the conserved heme-binding region ond the charge pair consensus of insect cytochrome P450s, two novel full-length P450 cDNAs, CYP6BB1 and CYP6P10, were cloned from the salt marsh mosquito Aedes sollicitons (Walker). CYP6BB1 and CYP6P10 had open reading frames of 1,518 and 1,521 nucleotides encoding 506 and 507 amino acid residue proteins, respectively. Several alleles with amino acid substitutions were found both in CYP6BB1 and CYP6P10. The deduced proteins are typical microsomal P450s sharing signature sequences with other insect CYP6 P450s. Sequence analysis showed that both CYP6BB1 ond CYP6P10 shared highest sequence identities with P450 CYP6P4, 56% and 65%, respectively. Phylogenetic analysis showed both CYP6BB1 and CYP6P10 were grouped into the clade containing several P450s from subfamily CYP6P. Real-time RT-PCR analysis showed CYP6BB1 but not CYP6P10 transcription in females was significantly increased 24 h after a blood meal. Neither CYP6BB1 nor CYP6P10 were life stage or gender specific. Protein expression experiments are needed to determine the functions of these proteins.
