This neurotransmitter serves somewhat the same purpose as glycine.
One type of receptor for this neurotransmitter is defined by being insensitive to bicuculline and baclofen. The enzyme that creates this molecule from an amino acid with an acidic side chain requires pyridoxal phosphate, or Vitamin B6, as a cofactor. An potent agonist of one of its receptors is found in the Amanita mushroom genus and is muscimol. This neurotransmitter serves somewhat the same purpose as glycine. The B type of its receptor is coupled to G proteins while the A type of its receptor is a pentameric ligand-gated chloride channel to which benzodiazepines bind. It is released by Purkinje cells and is formed by decarboxylating glutamate. For 10 points, name this inhibitory neurotransmitter of the CNS.
