Neurotransmitter synthesis pathway enzyme

Neurotransmitter synthesis pathway enzymes are a broad group of enzymes responsible for catalyzing the biochemical reactions that produce neurotransmitters from precursor molecules. Each major small-molecule neurotransmitter—such as acetylcholine, dopamine, serotonin, norepinephrine, GABA (gamma-Aminobutyric acid), glutamate, and glycine—is synthesized by a specific set of enzymes. For example: - Glutamic acid decarboxylase converts glutamate into GABA. - Serine hydroxymethyltransferase converts serine into glycine. - Tyrosine hydroxylase is rate-limiting in catecholamine synthesis (dopamine/norepinephrine/epinephrine). These enzymes are essential for maintaining proper levels and balance between excitatory and inhibitory signals in neural circuits. Dysregulation or genetic defects affecting these pathways can contribute to neurological and psychiatric diseases such as Parkinson’s disease (dopaminergic deficit), epilepsy (GABAergic dysfunction), depression (monoaminergic imbalance), among others[1][2][3].
