General description

γ-aminobutyric acid (GABA) is an inhibitory neurotransmitter that binds selective transmembrane receptors, resulting in gating of ion channels in the central nervous system. GABA that is released from the receptors is degraded by GABA-transaminase. Gabaculine (3-Amino-2,3-dihydrobenzoic acid) is a neurotoxin that was first isolated from Streptomyces toyocaenis and is a conformationally constrained analog of GABA. Gabaculine inhibits GABA-transaminase, which results in an increase of endogenous GABA in the brain and spinal cord.

Biochem/physiol Actions

3-Amino-2,3-dihydrobenzoic acid hydrochloride potently and specifically inhibits GABA-transaminase (GABA-T), resulting in inhibited degradation of GABA. May inhibit glutamic acid decarboxylase (GAD), though it is 1000-fold more effective as a GABA-T inhibitor than as a GAD inhibitor.

gamma-Aminobutyric acid (GABA) and N-methyl-D-aspartate (NMDA) receptors are important targets for anesthetic action at the in vitro cellular level. Gabaculine is a GABA-trans-aminase inhibitor that increases endogenous GABA in the brain, and enhances GABA activity. We have recently shown that

Synthesis of 5-aminolevulinic acid (ALA) represents a rate limiting step in the tetrapyrrole biosynthetic pathway, and is regulated by metabolic feedback control of glutamyl-tRNA reductase (GluTR) activity. The FLU protein has been attributed to this regulation. Later in the biosynthetic

The metabolite 5-aminolevulinic acid (ALA) is an early committed intermediate in the biosynthetic pathway of heme and chlorophyll formation. In plants, 5-aminolevulinic acid is synthesized via a two-step pathway in which glutamyl-tRNA(Glu) is reduced by glutamyl-tRNA(Glu) reductase (GluTR) to glutamate

The biosynthesis of ansamycin antibiotics, like rifamycin B, involves formation of 3-amino-5-hydroxybenzoic acid (AHBA) by a novel variant of the shikimate pathway. AHBA then serves as the starter unit for the assembly of a polyketide which eventually links back to
