Figure 2.

Deduced amino acid sequences of 10 zebrafish odorant receptor molecule fragments fZOR1-10. Amino acids are depicted in one-letter code. The asterisk in fZOR7 stands for a stop codon that is also present in the gene and may be due to a recent inactivation of the gene, since mRNA for fZOR7 is present at normal levels. Sequences were aligned using the UPMGAA algorithm (GCG). Dots indicate gaps inserted for optimal alignment. The predicted positions of transmembrane domains IV–VII are underlined. Amino acids conserved 80% or more are depicted by inverse letters.
