Figure 2From: Modular evolution of glutathione peroxidase genes in association with different biochemical properties of their encoded proteins in invertebrate animalsSelenocysteine insertion sequence (SECIS) motifs found in the platyhelminth GPx genes. The structures are predicted from the nucleotide sequences corresponding to the 3'-untranslated regions of the respective mRNAs. The typical secondary structure of the mammalian SECIS is also presented for comparison [31].Back to article page
