Cryo-EM structures of the channelrhodopsin ChRmine in lipid nanodiscs
Nature Communications, 2022 ChRmine is a bacteriorhodopsin-like cation channelrhodopsin (BCCR). Here, the authors present cryo-EM structures of ChRmine in apo- and retinal-bound forms to provide insight into channel activity in a BCCR and facilitate engineering of ChRmine-based ...

Chromophore equilibria in bacteriorhodopsin
Biophysical Journal, 1979 An investigation of the dark equilibria between different chromophores of bacteriorhodopsin (BR) and studies of the kinetics of their interconversion and photochemical activity have led to the following conclusions. (a) A component of the 605-nm chromophore of BR decays in the millisecond range and is likely to be identical to the intermediate O of the

Lipid composition of integral purple membrane by 1H and 31P NMR
Journal of Lipid Research, 2005 In the purple membrane (PM) of halobacteria, lipids stabilize the trimeric arrangement of bacteriorhodopsin (BR) molecules and mediate the packing of the trimers in a regular crystalline arrangement.
