Convergent evolution of animal and microbial rhodopsins [PDF]

RSC Advances, 2023
Rhodopsins, a family of photoreceptive membrane proteins, contain retinal as a chromophore and were firstly identified as reddish pigments from frog retina in 1876. Since then, rhodopsin-like proteins have been identified mainly from animal eyes. In 1971,

Ion-Pumping Microbial Rhodopsins [PDF]

Frontiers in Molecular Biosciences, 2015
Rhodopsins are light-sensing proteins used in optogenetics. The word rhodopsin originates from the Greek words rhodo and opsis, indicating rose and sight, respectively. Although the classical meaning of rhodopsin is the red-colored pigment in our eyes,

Fluorescence of the Retinal Chromophore in Microbial and Animal Rhodopsins [PDF]

International Journal of Molecular Sciences, 2023
Fluorescence of the vast majority of natural opsin-based photoactive proteins is extremely low, in accordance with their functions that depend on efficient transduction of absorbed light energy.

A Novel Color Switch of Microbial Rhodopsin

Biochemistry, 2023
Function of animal and microbial rhodopsins starts by light absorption of the retinal chromophore. The absorption maximum wavelength (λmax) of rhodopsins is determined by the energy gap between the electronically ground (S0) and first excited (S1) state ...

The Evolutionary Relationship between Microbial Rhodopsins and Metazoan Rhodopsins [PDF]

The Scientific World Journal, 2013
Rhodopsins are photoreceptive proteins with seven-transmembrane alpha-helices and a covalently bound retinal. Based on their protein sequences, rhodopsins can be classified into microbial rhodopsins and metazoan rhodopsins.

Microbial Rhodopsins

, 2022
The first microbial rhodopsin, a light-driven proton pump bacteriorhodopsin from Halobacterium salinarum (HsBR), was discovered in 1971. Since then, this seven-α-helical protein, comprising a retinal molecule as a cofactor, became a major driver of ...

Fluorescence Enhancement of a Microbial Rhodopsin via Electronic Reprogramming [PDF]

Journal of the American Chemical Society, 2018
The manuscript reports on two mutations of the photo-sensory protein Anabaena Sensory Rhodopsin and how these mutations modify the fluorescence quantum yield with respect to the wild-type protein.

Far-Red Absorbing Rhodopsins, Insights From Heterodimeric Rhodopsin-Cyclases [PDF]

Frontiers in Molecular Biosciences, 2022
The recently discovered Rhodopsin-cyclases from Chytridiomycota fungi show completely unexpected properties for microbial rhodopsins. These photoreceptors function exclusively as heterodimers, with the two subunits that have very different retinal ...

Engineering artificial photosynthesis based on rhodopsin for CO2 fixation [PDF]

Nature Communications, 2023
Microbial rhodopsin, a significant contributor to sustaining life through light harvesting, holds untapped potential for carbon fixation. Here, we construct an artificial photosynthesis system which combines the proton-pumping ability of rhodopsin with ...

Expression analysis of microbial rhodopsin-like genes in Guillardia theta.

PLoS ONE, 2020
The Cryptomonad Guillardia theta has 42 genes encoding microbial rhodopsin-like proteins in their genomes. Light-driven ion-pump activity has been reported for some rhodopsins based on heterologous E. coli or mammalian cell expression systems.
