Bacterial Glutathione Transferase
Bacterial glutathione transferases (GSTs; EC 2.5.1.18) are part of a superfamily of enzymes that play a crucial role in cellular detoxification.Liu S, Liu F, Jia H, Yan Y, Wang H, Guo X, Xu B. 2016. A glutathione S-transferase gene associated with antioxidant properties isolated from ''Apis cerana cerana''. Scientific National 103: 43 The primary role of GSTs is to catalyze the conjugation of glutathione (GSH) with the electrophilic centers of a wide variety of molecules. The most commonly known substrates of GSTs are xenobiotic synthetic chemicals. There are also classes of GSTs that utilize glutathione as a cofactor rather than a substrate. Often these GSTs are involved in reduction of reactive oxidative species toxic to the bacterium. Conjugation with glutathione receptors reders toxic substances more soluble, and therefore more readily exocytosed from the cell. Classes and roles Bacterial glutathione transferases are widely distributed in aerobic bacteria and are class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacterial GST
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulp ...
