Abstract
Neutron diffraction and time-resolved laser-spectroscopic experiments on the light-driven proton-pump bacterio-rhodopsin revealed the locati on of water molecules and their functional importance. About seven wat er molecules in the proton pathway across this membrane protein were d etermined at 15% rel. humidity in the ground state.
