Chain A,B (DCE1_HUMAN | Q99259)

molecular function
	GO:0016831	carboxy-lyase activity	Catalysis of the nonhydrolytic addition or removal of a carboxyl group to or from a compound.
	GO:0003824	catalytic activity	Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
	GO:0016595	glutamate binding	Interacting selectively and non-covalently with glutamate, the anion of 2-aminopentanedioic acid.
	GO:0004351	glutamate decarboxylase activity	Catalysis of the reaction: L-glutamate = 4-aminobutanoate + CO2.
	GO:0016829	lyase activity	Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
	GO:0047485	protein N-terminus binding	Interacting selectively and non-covalently with a protein N-terminus, the end of any peptide chain at which the 2-amino (or 2-imino) function of a constituent amino acid is not attached in peptide linkage to another amino-acid residue.
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
	GO:0046982	protein heterodimerization activity	Interacting selectively and non-covalently with a nonidentical protein to form a heterodimer.
	GO:0030170	pyridoxal phosphate binding	Interacting selectively and non-covalently with pyridoxal 5' phosphate, 3-hydroxy-5-(hydroxymethyl)-2-methyl4-pyridine carboxaldehyde 5' phosphate, the biologically active form of vitamin B6.
biological process
	GO:0019752	carboxylic acid metabolic process	The chemical reactions and pathways involving carboxylic acids, any organic acid containing one or more carboxyl (COOH) groups or anions (COO-).
	GO:0007268	chemical synaptic transmission	The vesicular release of classical neurotransmitter molecules from a presynapse, across a chemical synapse, the subsequent activation of neurotransmitter receptors at the postsynapse of a target cell (neuron, muscle, or secretory cell) and the effects of this activation on the postsynaptic membrane potential and ionic composition of the postsynaptic cytosol. This process encompasses both spontaneous and evoked release of neurotransmitter and all parts of synaptic vesicle exocytosis. Evoked transmission starts with the arrival of an action potential at the presynapse.
	GO:0009449	gamma-aminobutyric acid biosynthetic process	The chemical reactions and pathways resulting in the formation of gamma-aminobutyric acid (GABA, 4-aminobutyrate), an amino acid which acts as a neurotransmitter in some organisms.
	GO:0006538	glutamate catabolic process	The chemical reactions and pathways resulting in the breakdown of glutamate, the anion of 2-aminopentanedioic acid.
	GO:0006540	glutamate decarboxylation to succinate	The chemical reactions and pathways resulting in the formation of succinate from glutamate. Also known as GABA (gamma-aminobutyrate) shunt since it channels glutamate into the TCA cycle bypassing two steps of that cycle. There are three enzymes involved in the GABA shunt: glutamate decarboxylase (GAD), GABA aminotransferase (GABA-TA), and succinate semialdehyde dehydrogenase (SSADH). These three enzymes acting in concert to convert glutamate into succinate. The GABA shunt is predominantly associated with neurotransmission in the mammalian brain. It is also present in nonneuronal cells, in plants, in unicellular eukaryotes, and in prokaryotes.
	GO:0042136	neurotransmitter biosynthetic process	The chemical reactions and pathways resulting in the formation of any of a group of substances that are released on excitation from the axon terminal of a presynaptic neuron of the central or peripheral nervous system and travel across the synaptic cleft to either excite or inhibit the target cell.
	GO:0007269	neurotransmitter secretion	The regulated release of neurotransmitter from the presynapse into the synaptic cleft via calcium regualated exocytosis during synaptic transmission.
	GO:0018352	protein-pyridoxal-5-phosphate linkage	The formation of a linkage between a protein amino acid and pyridoxal-5-phosphate.
	GO:0042493	response to drug	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.
cellular component
	GO:0061202	clathrin-sculpted gamma-aminobutyric acid transport vesicle membrane	The lipid bilayer surrounding a clathrin-sculpted gamma-aminobutyric acid transport vesicle.
	GO:0005622	intracellular	The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
	GO:0005886	plasma membrane	The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
	GO:0048786	presynaptic active zone	A specialized region of the plasma membrane and cell cortex of a presynaptic neuron; encompasses a region of the plasma membrane where synaptic vesicles dock and fuse, and a specialized cortical cytoskeletal matrix.
	GO:0012506	vesicle membrane	The lipid bilayer surrounding any membrane-bounded vesicle in the cell.
