Abstract: Sulfide detoxification can be catalyzed by ancient membrane-bound flavoproteins, sulfide:quinone oxidoreductases (Sqr), which have important roles in sulfide homeostasis and sulfide-dependent energy conservation processes by transferring electrons from sulfide to respiratory or photosynthetic membrane electron… read more here.

Abstract: We describe here a simple strategy to characterize transport specificity of NADH:quinone oxidoreductases, using Na+-translocating (NQR) and H+-translocating (NDH-1) enzymes of the soil bacterium Azotobacter vinelandii as the models. Submillimolar concentrations of Na+ and Li+… read more here.
