Gamma-glutamyl transpeptidase in transgenic tobacco plants. Cellular localization, processing, and biochemical properties.
gamma-Glutamyl transpeptidase (gamma-GT) is a ubiquitous enzyme that catalyzes the first step of glutathione (GSH) degradation in the gamma-glutamyl cycle in mammals. A cDNA encoding an Arabidopsis homolog for gamma-GT was overexpressed in tobacco (Nicotiana tabacum) plants. A high level of the membrane-bound gamma-GT activity was localized outside the cell in transgenic plants. The overproduce...
متن کاملA gamma-glutamyl transpeptidase-independent pathway of glutathione catabolism to glutamate via 5-oxoproline in Arabidopsis.
The degradation pathway of glutathione (GSH) in plants is not well understood. In mammals, GSH is predominantly metabolized through the gamma-glutamyl cycle, where GSH is degraded by the sequential reaction of gamma-glutamyl transpeptidase (GGT), gamma-glutamyl cyclotransferase, and 5-oxoprolinase to yield glutamate (Glu) and dipeptides that are subject to peptidase action. In this study, we ex...
متن کاملAnti-tumor Activity and Cell Cycle Arrest of a New Diterpene Ester from Daphne mucronata Using K562 Cells
In our search for new anticancer medicinal plants, the antiproliferative activity of the methanol extract of Daphne mucronata (Thymelaeaceae) was evaluated using human myelogenous leukemia K562 cells. The cells responded to plant treatments in a dose dependent manner and the IC50 of the crude extract (equivalent to 1 g of plant leaves powder per ml) and the purified active component were found ...

Background: A field study on the transfer of primordial radionuclides 238U, 232Th, 40K and fallout radionuclides 210Po in different plant species in tropical forest of western Ghats environment is presented. Material and Methods: The Top storey, Second storey, Shrubs and epiphytic plant species were chosen and concentration of these radionuclides in plant and soil were measured by employing gam...
متن کاملA System Dynamics Model to Evaluate Emissions in A Combined Cycle Power Plant
Environment and the need to protect and care for it, is one of the main concerns of industrial development in todaychr('39')s society; and air pollution is one of the most noticeable and tangible causes of it. The increasingly growth of the industry has led to the production and diffusion of gaseous pollutants into the air and among them; thermal power plants are one of the most important sourc...
