Alignment of members of the 5' nucleotidase family from D. pseudoobscura, Bos taurus, Rattus rattus, Glossina morsitans morsitans and the horse fly Chrysops spp. The numbers following the species abbreviations indicate the NCBI accession number for each protein. Notice, in the haematophagous dipteran sequences, the absence of the carboxyterminal region where the glycophophatidylinositol anchor normally attaches (indicated by the blue box). Symbols above the alignment indicate standard ClustalW nomenclature: (*) identity, (:) high conservation and (.) conservation.
