Photoisomerization pathway of the microbial rhodopsin chromophore in solution

Photochemical & Photobiological Sciences
AbstractPhotoisomerization is a key photochemical reaction in microbial and animal rhodopsins. It is well established that such photoisomerization is highly selective; all-trans to 13-cis, and 11-cis to all-trans forms in microbial and animal rhodopsins, respectively.

Anabaena sensory rhodopsin a photochromic color sensor at 2.0 A

, 2004
Microbial sensory rhodopsins are a family of membrane embedded photoreceptors in prokaryotic and eukaryotic organisms. Structures of archaeal rhodopsins, which function as light driven ion pumps or photosensors, have been reported.

Origin of the unique topology of the triangular water cluster in Rubrobacter xylanophilus rhodopsin

Biophysics and Physicobiology
The crystal structure of Rubrobacter xylanophilus rhodopsin (RxR) reveals a triangular cluster of three water molecules (W413, W415, and W419) at the extracellular proton-release site, near Glu187 and Glu197.

Engineering yeast with a light-driven proton pump system in the vacuolar membrane

Microbial Cell Factories
Background The supply of ATP is a limiting factor for cellular metabolism. Therefore, cell factories require a sufficient ATP supply to drive metabolism for efficient bioproduction.

Ecological Effects Of Rhodopsin Phototrophy In Antarctic Sea Ice

Despite its extreme cold temperatures and being in complete darkness for much of the year, Antarctic sea ice harbours a diverse and robust microbial community that is important for pelagic and benthic ecosystems in ice-dominated regions.

Production and Structural Dynamics of Microbial Rhodopsins

, 2019
Rhodopsins are a family of membrane proteins that are found in a wide range of organisms and provide them with the ability to sense and react to light. When light is absorbed by these proteins, structural changes occur that initiate the pumping of protons, opening of a channel or signal transfer.

Excitation-wavelength- and protonation-dependent multiple photoreaction pathways in TAT rhodopsin from femtoseconds to seconds

TAT rhodopsin is a member of the microbial rhodopsin family, a large group of seven-transmembrane photoreceptive proteins that bind an all-trans-retinal chromophore.

Imaging Voltage with Microbial Rhodopsins

Imaging Voltage with Microbial Rhodopsins
Membrane potential is the critical parameter that reflects the excitability of a neuron, and it is usually measured by electrophysiological recordings with electrodes. However, this is an invasive approach that is constrained by the problems of lacking spatial resolution and genetic specificity.
