For 10 points, name this enzyme which breaks down a certain neurotransmitter at the neuromuscular junction.
Polymorphisms at codon-322 of this protein distinguish the Yt blood groups. A version of this enzyme found in Torpedo californica was used to deduce its crystal structure. This enzyme uses its ColQ tail subunit to tetramerize. Inhibition of this enzyme is used to reverse the effects of the anesthetics rocuronium and vecuronium. This enzyme is reversibly inhibited by edrophonium, and inhibitors of this enzyme in eye drop form are used to treat glaucoma. Organophosphate toxicity inhibits this enzyme, which can be regenerated by pralidoxime and inhibited by (*) neostigmine, which is commonly used to treat myasthenia gravis. Autoinjectors containing atropine are used in cases when this enzyme is inhibited by VX, Sarin, or other nerve agents. For 10 points, name this enzyme which breaks down a certain neurotransmitter at the neuromuscular junction.
Polymorphisms at codon-322 of this protein distinguish the Yt blood groups.
