Divergence of AMP Deaminase in the Ice Worm Mesenchytraeus solifugus (Annelida, Clitellata, Enchytraeidae)

Table 2

Amino acid composition changes in ice worm AMPD. Number indicate gains (+) or losses (−) in ice worm AMPD in comparison with sequences among clitellates (E. albidus, L. variegatus ) and other mesophilic eucaryotes (A. thaliana , H. sapiens , D. melanogaster , C. elegans). Molecular weight change (Mwt) is in Dalton (Da).
