The Function of Gas Vesicles in Halophilic Archaea and Bacteria: Theories and Experimental Evidence
Life, 2012 A few extremely halophilic Archaea (Halobacterium salinarum, Haloquadratum walsbyi, Haloferax mediterranei, Halorubrum vacuolatum, Halogeometricum borinquense, Haloplanus spp.) possess gas vesicles that bestow buoyancy on the cells. Gas vesicles are also

Cation binding by bacteriorhodopsin [PDF]
Proceedings of the National Academy of Sciences, 1985 We have found that extensively washed purple membrane has about 1 calcium and 3-4 magnesium ions bound per bacteriorhodopsin molecule. When these divalent cations are removed by any of a variety of means, the pigment changes its color from purple to blue (λ max ≈ 600 nm).

Energy transfer from retinal to amino acids — a time-resolved study of the ultraviolet emission of bacteriorhodopsin [PDF]
, 1986 Two-step excitation of retinal in bacteriorhodopsin by visible light is followed by an energy transfer to amino acids that is seen as fluorescent emission around 350 nm.

Journal of Physical Chemistry Letters, 2019 Bacteriorhodopsin is a prototypical photoreceptor protein that functions as a light-driven proton pump. The retinal chromophore of bacteriorhodopsin undergoes C13═C14 trans-to-cis isomerization upon photoexcitation, and it has been believed to be the ...

Quantifying the Initial Unfolding of Bacteriorhodopsin Reveals Retinal Stabilization.
Angewandte Chemie, 2019 The forces that stabilize membrane proteins remain elusive to precise quantification. Particularly important, but poorly resolved, are the forces present during the initial unfolding of a membrane protein, where the most native set of interactions is ...

Probing a polar cluster in the retinal binding pocket of bacteriorhodopsin by a chemical design approach. [PDF]
PLoS ONE, 2012 Bacteriorhodopsin has a polar cluster of amino acids surrounding the retinal molecule, which is responsible for light harvesting to fuel proton pumping.
