Alignment of the three putative aquaporin clones identified in the libraries. Transmembrane domains are marked above the sequence (TM6 is only partial in both CL138 and sb_ 005_09I19). Red lines denote the two conserved NPA motifs of the aquaporin family. Only CL138 has conserved the site for N-glycosylation . Red asterisks below the consensus line identify 13/14 amino acids conserved throughout the mammalian aquaporin family, as outlined in previous protein fragment analyses . B) Percentage amino acid identities between the different springtail aquaporin clones. Figures in brackets are the percentage amino acid similarities. Each clone was clipped to the same size when performing the calculations.
