CLUSTALX alignment of the predicted amino acid sequences for F10D2.2, F10D2.5, F10D2.6,F10D2.7, F10D2.8, and F09G2.6. Each of these genes appears to encode UDP-glucuronosyl transferase. The amino acids in the gap in the alignment for F10D2.8 (positions 120–174) are encoded by an extension of the predicted exon 2 into nonhomologous, presumably intronic DNA. No vestiges of the missing coding region can be seen in this 175-bp second intron. The deletion of this conserved region suggests that F10D2.8 is a pseudogene. Apparent deletions or insertions for the other sequences in the alignment can be accounted for by errors in gene structure prediction, suggesting that the other annotated genes in this cluster have intact coding regions. Extra, nonhomologous amino acids predicted at the amino terminus forF10D2.2 and F09G2.6 have been removed for this alignment.
