Abstract excerpt

Helicobacter pylori is an organism known to colonize the normal human stomach. Previous studies have shown that the bacterium does this by elevating its periplasmic pH via the hydrolysis of urea. However, the value of the periplasmic pH was calculated indirectly from the proton motive force equation. To measure the periplasmic pH directly in H. pylori, we fused enhanced green fluorescent protein (EGFP) to the...
