Table 3. Percent identities and scores comparing Repeat 1 protein orthologs and paralogs
A: Data suggest that the zebrafish and fugu IRBP loci as a pair of orthologs (Z1-F1 and Z2-F2) diverged more recently than Gene 1 and Gene 2 paralogs (Z1-Z2 and F1-F2). The paralogs Z1-F2 and Z2-F1 are consistent with the paralogs Z1-Z2 and F1-F2, in percent identity and score, suggesting that there has been no recent gene conversion. The greater conservation of the orthologs than the paralogs suggests that the divergence of Gene 1 from Gene 2 was an early event in teleost evolution, as the divergence of fugu and zebrafish was in the moderate to distant past in the history of the teleosts. B: Pairwise comparisons between the indicated two versions of Repeat 1 were conducted using BL2SEQ at the Biology Workbench (San Diego Supercomputer Center). The percent identity is indicated in the lower left half of each table. The raw bit score is indicated in the upper left right of the table.
