Light-induced pH changes inside bacteriorhodopsin vesicles as measured by 31 P NMR.
31P NMR has been used to measure light-induced pH changes inside bacteriorhodopsin vesicles containing entrapped sodium glucose-6-phosphate. Reversible light-induced pH changes were observed at various pH values. The results indicate that our vesicle preparations were not homogeneous with respect to the generation of pH gradients.
