Figure 2From: The globin gene family of the cephalochordate amphioxus: implications for chordate globin evolutionAmino acid sequence alignment of inferred B. floridae globins (BflGb) and human (Hsa) globins Ngb, Cygb and Mb. The globin α-helical structure is drawn on top of the alignment. Conserved positions are shaded. Intron positions in globin genes are indicated by arrows below the protein alignment and the intron presence in the respective gene variants is given.Back to article page
