Reengineering Redox Sensitive GFP to Measure Mycothiol Redox Potential of Mycobacterium tuberculosis during Infection

Mycobacterium tuberculosis (Mtb) survives under oxidatively hostile environments encountered inside host phagocytes. To protect itself from oxidative stress, Mtb produces millimolar concentrations of mycothiol (MSH), which functions as a major cytoplasmic redox buffer. Here, we introduce a novel system for real-time imaging of mycothiol redox potential (EMSH ) within Mtb cells during infection....

INVESTIGATING REDOX POTENTIAL WITH REDOX-SENSITIVE GFP INDICATORS IN REPRODUCTIVE TISSUES OF A. thaliana

Redox homeostasis is a fundamental property of living cells and actively responds to cellular metabolism and external stimuli. In all cells, small molecules capable of thiol-disulphide exchange such as glutathione (GSH) are abundant and are thought to act as buffers in redox equilibrium [1]. Given the importance and the general interest in cellular redox processes, a noninvasive method that det...

How to Change the Redox Potential of Guanine?

Due to some important applications of guanine electrode in scientific and technology research such as electro-chemical DNA based biosensors, and a problem of high redox potential of guanine (0.81 V), our research study concentrates on reducing guanine redox potential by substituting Cu, Ag, Au, CH3, C2H5 and Cl on sites of 1, 2 and 9 of guanine. A 5.0% reduction...

Exploring the redox balance inside gram-negative bacteria with redox-sensitive GFP.

Aerobic bacteria are continuously fighting potential oxidative stress due to endogenous and exogenous reactive oxygen species (ROS). To achieve this goal, bacteria possess a wide array of defenses and stress responses including detoxifying enzymes like catalases and peroxidases; however until now, the dynamics of the intra-bacterial redox balance remained poorly understood. Herein, we used redo...

Collectorless flotation of Chalcocite by controlling redox potential

Using microflotation method, this study explored the collectorless flotation of Chalcocite and its dependence on the redox potential of pulp . Electrochemical studies were performed by cyclic voltammetry  in specific potential ranges and at different pH values. The results show that significant floatability of Chalcocite occurs in the specific reducing conditions. By increasing potentials, on t...
