Alignment of human, rat, chicken, beetle (Triboleum castaneum), fly (Drosophila melanogaster), bee and flea acid phosphatase sequences. The red letters over yellow background indicate amino acids found in the active center of rat and human enzymes. Other yellow background indicated identical (in bold) or conserved amino acids. The bars indicate regions of insertion/deletion when the flea and remaining sequences are compared. Cysteines are shown in white font over black background.
