Fig. 3. Hydropathy plot of (A) crayfish cardiac muscle SERCA (present study;
accession no. AAB82291) in comparison with (B) crayfish axial muscle
(Zhang et al., 2000; accession
no. AAB8229), (C) Artemia SERCA 5.2 kb isoform
(Escalante and Sastre, 1993;
accession no. CAA51262), (D) Artemia SERCA 4.5 kb isoform
(Palmero and Sastre, 1989;
accession no. P35316), (E) rat SERCA2b
(Lytton et al., 1989;
accession no. P11057) and (F) rat SERCA2a
(Brandl et al., 1986; accession
no. P11508). Hydrophobicity values were determined by the method of Kyte and
Doolittle (1982) using a
window of 12 residues (MacDNASIS, Rainbow Technologies). Putative
transmembrane domains are numbered based on the model of Brandl et al.
(1986). The arrows indicate the
extra potential transmembrane domain.
