Summary
| Description |
English: Crystal structure of the Aplysia californica acetylcholine-binding protein pentamer in complex with pinnatoxin A (yellow). The protein chains are shown in different colors to highlight the position of the pinnatoxin at the inter-subunit interfaces. Pinnatoxins are macrocyclic molecules which were discovered in shellfish and are produced by dinoflagellates. They are highly toxic due to their interactions with nicotinic acetylcholine receptors, for which the Aplysia californica acetylcholine-binding protein is a model.
