1 Acetylcholine Receptor Binding Toxins
Bungarus multicinctus: κ-bungarotoxin toxin source Link to BioQUEST Lesson Hypothesis: Similar functioning proteins that bind the ACh receptors will have similar amino acid sequences. Naja naja: α-cobra toxin source Results: *Overlay: α-cobra toxin a (Y), κ-bungarotoxin (B), Cobratoxin (G), Erabutoxin (O) ACh Receptor *Phylogenetic Tree: Conclusion: Four (4) toxins that affect ACh receptors were found to be closely related evolutionarily resulting in proteins that have structural areas of similarity in their amino acid sequences. *Associated Amino Acid Residue Sequences: α-bungarotoxin κ-bungarotoxin Cobratoxin Erabutoxin
