decarboxylase/glycine max

Unlike other eukaryotes, which synthesize polyamines (PA) only from ornithine, plants possess an additional pathway utilizing arginine as a precursor. In this study, we have identified cDNA clones coding for a Glycine max ornithine decarboxylase (ODC, EC 4.1.1.7) and an arginine decarboxylase (ADC,

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

The activity of lysine decarboxylase was studied in 3-day-old soybean (Glycine max (L.) Meer cv. Sakai) seedlings also in relation to light conditions. Lysine decarboxylase activity was mainly localized in the roots and to a lesser extent in the hypocotyls and was detectable in both the soluble and

Lysine decarboxylase (EC 4.1.1.18) was purified 364-fold from 2-day-old soybean (Glycine max) axes. The enzyme was a monomeric protein having a molecular mass of 95,000 Da and an isoelectric point of 4.0. The K(m) for L-lysine was 1.17 mM. The optimal temperature and pH of the enzyme were 37 degrees

Arginine decarboxylase (EC 4.1.1.19) was purified from soybean, Glycine max, hypocotyls by a procedure which includes ammonium sulfate fractionation, acetone precipitation, gel filtration chromatography, and affinity chromatography. Using this procedure, ADC was purified to one band in

Pyruvate decarboxylase (PDC, EC 4.1.1.1) and alcohol dehydrogenase (ADH, EC 1.1.1.1) are responsible for the anaerobic production of acetaldehyde and ethanol in higher plants. In developing soybean embryos, ADH activity increased upon imbibition and then declined exponentially with development, and

We cloned a rice cDNA encoding a putative arginine decarboxylase (ADC) protein, a key enzyme involved with putrescine (Put) biosynthesis in plants. The isolated full-length cDNA (OsADC1) contains an insert consisting of 2451 bp. The longest open reading frame within encodes a putative protein of 702

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.)

Active polyamine biosynthesis occurs in the embryonic axis, but not in the cotyledons, during germination of Glycine max (L.) cv Williams seeds and subsequent growth of the young seedlings. The hypocotyl and radicle synthesize and accumulate considerable amounts of cadaverine (Cad) and putrescine

S-Adenosylmethionine decarboxylase (EC 4.1.1.19) was purified to homogeneity from the cytosol of soybean (Glycine max) axes by ammonium sulfate fractionation, DEAE-Sepharose and methylglyoxalbis(guanylhydrazone)-Sepharose 6B chromatographies. The enzyme was free from diamine oxidase activity. The

A new active S-adenosylmethionine decarboxylase (EC 4.1.1.50) (SAMDC II) was extracted from soybean (Glycine max) axes. The enzyme was purified to homogeneity by ammonium sulfate fractionation, DEAE-Sepharose and methylglyoxalbis(guanylhydrazone) (MGBG)-Sepharose 6B chromatographies. The molecular

Arginine decarboxylase (ADC) is one of the key enzymes in the biosynthesis of putrescine in plants. The regulation of its activity depends on the physiological condition, developmental stage, and type of tissue. We have cloned ADC cDNA from soybean (Glycine max) hypocotyls to understand the

When the polyamine content of soybean (Glycine max) seeds was examined during the early stages of germination, the major polyamine in the cotyledons was found to be spermidine, followed by spermine; while very low concentrations of cadaverine were found. In the embryonic axes, however, cadaverine

Soya bean (Glycine max) and grass pea (Lathyrus sativus) seeds are important sources of dietary proteins; however, they also contain antinutritional metabolite oxalic acid (OA). Excess dietary intake of OA leads to nephrolithiasis due to the formation of calcium oxalate crystals in kidneys. Besides,

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
