Figure 3

Sequence logos of zebrafish and mouse OR families. Conservation of predicted amino acid sequence for the zebrafish (a) and mouse (b) OR repertoires is shown graphically (see the text). Y axis, information content. X axis, residue position. For this analysis, positions with gaps in more than 95% of sequences, as well as poorly aligned N- and C-terminal sequences, were removed. Positions in the species-specific logos are identical according to this alignment. The logo was generated from this alignment using the program WebLogo (G.E. Crooks, G. Hon, J.-M. Chandonia and S.E. Brenner, personal communication), available at http://weblogo.berkeley.edu/.
