Fig. 10. Alignment (ClustalX) of D. melanogaster OBP amino acid sequences. Drosophila sequences are those identified in Table 1; locus 6 genes were excluded because of significant divergence from the other OBPs. Other included proteins showed a significant relationship to the Drosophila proteins by Blast analysis: CAB64650, CAB64649 and CAB64645 are serum proteins of the medfly Ceratitis capitata, (Christophides et al., 2000), LAP (AF091118) is an OBP from the hemipteran Lygus lineolaris (Vogt et al., 1999) and ABPXMsex (AF117577) is an OBP from M. sexta (Robertson et al., 1999). This alignment preserved the relationships between six conserved cysteines, noted by ‘X’. Exon domains are alternately in bold and underlined.
