Amino acid sequence alignment of Calliphora (Cv) and Drosophila (Dm) rhodopsins. Amino acid sequence alignment of Calliphora (Cv) and Drosophila (Dm) rhodopsins. Sequences are shown in single letter code. The seven transmembrane domains (TM1–TM7) are indicated in grey. Black boxes highlight amino acids conserved in all sequences. Accession numbers of the sequences are: DmRh1, P06002; DmRh3, P04950; DmRh4, P08225; DmRh5, P91657; DmRh6, O01668; CvRh1, J05596; CvRh3, Af878411; CvRh5, Af878412; CvRh6, Af878413.
