摘要: Publisher Summary The bacteriorhodopsins, which are proton pumps, and the halorhodopsins, chloride ion constitute a class of unique light-energy-transducing systems. They serve bioenergetic functions driven more commonly by redox reactions or chlorophyll-based photosynthesis in other kinds membranes. general interest intense voluminous research this field originated instead from expectation that study these simple active transport systems, based on light-induced isomerization retinal small integral membrane proteins, would reveal principles translocation mechanisms energy coupling ionic pumps. residues second category must relate to differences inherent fact transfer requires different functional groups than protein. arrangement bacteriorhodopsin into trimers two-dimensional extended hexagonal lattice formed has made it possible describe structure protein with electron diffraction method.
