Question: amino acid sequences...

Question details
Amino acid sequences
Animals using toxic peptides and proteins for predation or defense typically depend on specialized morphological structures, like fangs, spines, or a stinger, for effective intoxication. Here we show that amphibian poisons instead incorporate their own molecular system for toxin delivery to attacking predators. Skin-secreted peptides, generally considered part of the amphibian immune system permeabilize oral epithelial tissue and enable fast access of cosecreted toxins to the predators bloodstream and organs. This absorption-enhancing system exists in at least three distantly related frog lineages and is likely to be a widespread adaptation, determining the outcome of predator-prey encounters in hundreds of species. Here is the simplified amino acid sequence for Bombina ortienalis toxin bombesin (Bom) QQRLGNQWAVGHLM. Hand-draw the peptide chain labeling each amino acid with the 1, 3 letter abbreviation and full name. (20 points) Here is the simplified amino acid sequence for the Phyllomedusa sauvagii antimicrobial peptide dermaseptin-S1: ALWKTMLKKLGTMALHAGAALGAAADTISQGTQ. Hand-draw the peptide chain labeling each amino acid with the 1, 3 letter abbreviation and full name. (40 points) 1. 2.
