摘要：

Hexagonal microcrystals of bacteriorhodopsin embedded in a lipidic cubic phase have been investigated by time-resolved FT-IR and resonance Raman spectroscopy. Retinal isomerization, conformational changes in the protein backbone and proton translocation are virtually indistinguishable from those in the native membrane. The protein is thus fully active in three-dimensional crystals. (C) 1998 Academic Press.
