Hemocyanins are large copper-containing respiratory proteins found in many arthropod species. Scorpions and orthognath spiders possess a highly conserved 4 x 6-mer hemocyanin that consists of at least seven distinct subunit types (termed a to g). However, many "modern" entelegyne spiders such as Cupiennius salei differ from the standard arachnid scheme and have 2 x 6-mer hemocyanins. Here we report the complete primary structure of the 2 x 6-mer hemocyanin of C. salei as deduced from cDNA… CONTINUE READING
