A Different initial resting states of the same microbial retinal protein (MRP), i.e. bacteriorhodopsin (BR), including dark-adapted (DA, in gray), light-adapted (LA, in blue) and K590 photo-intermediate (K, in red). The gray cube and the shading rectangles show the membrane and embedded chromophoric species inside the active site of corresponding protein, respectively. B The corresponding chromophoric species.
