FIGURE 1.

Comparison of the C. maenas hemoglobin with other arthropod globins. The secondary structure of the D. melanogaster hemoglobin (DmeHb) is superimposed in the upper row. The α-helices are designated A through H, and conserved amino acids are shaded. The globin consensus numbering is given below the sequences. The two intron positions B12.2 and E11.0 in the CmaHb gene are indicated by black arrows, the N-terminal glycine predicted for protein N-myristoylation is marked by an asterisk. DmaHb_1, D. magna hemoglobin domain 1, DmaHb_2, D. magna hemoglobin domain 2; CttHbVI, Chironomus thummi thummi hemoglobin VI.
