glutamate decarboxylase/glycine max

Glutamate decarboxylase (GAD) is an enzyme that catalyzes the production of gamma-amino butyric acid (GABA) from glutamate through a decarboxylation reaction. A full-length cDNA encoding glutamate decarboxylase (GmGAD1) was isolated from germinating soybean seeds (Glycine max [L.] Merr.). The GmGAD1

Recently, we provided preliminary evidence for calcium (Ca2+)/calmodulin (CaM) stimulation of plant glutamate decarboxylase (GAD; EC 4.1.1.15). In the present study, a detailed characterization of the phenomenon is described. GAD was partially purified from various soybean (Glycine max L. Merr.)

We investigated the effects of exogenous spermidine (Spd) on the physiological status, γ-aminobutyric acid (GABA) synthase activity, and gene expressions in germinating soybeans under NaCl stress. The results show that Spd significantly increases sprout growth and biomass, decreases malonaldehyde

Gamma-aminobutyric acid (GABA), a nonproteinous amino acid with some benefits on human health, is synthesized by GABA-shunt and the polyamine degradation pathway in plants. The regulation of Ca2+ and aminoguanidine on GABA accumulation in germinating soybean (Glycine max L.) under hypoxia-NaCl

The subcellular localization of enzymes involved in the 4-ami-nobutyrate shunt was investigated in protoplasts prepared from developing soybean [Glycine max (L.) Merrill cv Maple Arrow] cotyledons. Protoplast lysate was fractionated by differential and continuous Percoll-gradient centrifugation to

Soybean (Glycine max [L.] Merr) leaves contain a low level (0.05 micromole per gram fresh weight) of gamma-aminobutyric acid (Gaba) but the concentration of this non-protein amino acid increased to 1 to 2 micromoles per gram fresh weight within 5 minutes after transfer of plants or detached leaves

We studied the effects of drying of immature seeds of vegetable soybean (Glycine max L. Merrill) on the accumulation of gamma-aminobutyrate (GABA) in the seeds. GABA accumulated after heat-drying, with the maximum at 40°C. The GABA content (447.5 mg/100 g DW) increased to more than 5 times the value
