【 摘 要 】

Purple membranes oriented and immobilized in gel were soaked in solutions containing different monoamines and diamines. The flash-excited electric signals showed a reversal of the direction of the charge motion in bacteriorhodopsin in the case of diamines which was interpreted as the reversal of the proton pump. Monoamines had negligible influence on the electric signals. The influence of tetramethylethylenediamine was also studied in detail.
