Commonly synthesized from glutamate, it plays a similar role to glycine in the central nervous system.
An analog of this compound, vigabatrin, mimics its effects and inhibits this compound's catalysis, and in Little's Disease, muscles cannot properly absorb this compound, leading to cerebral palsy. Medium spiny neurons secrete this compound, and its activation causes cells to remain in the (*) S-phase. The synthesis of this compound requires the vitamin B6 derivative pyridoxal pyrophosphate, and benzodiazepines enhance its effects. Commonly synthesized from glutamate, it plays a similar role to glycine in the central nervous system. For 10 points, name this principal inhibitory neurotransmitter.
