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.

Convergent evolution of animal and microbial rhodopsins. [PDF]
RSC Adv, 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,

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.

Biochemical Analysis of Microbial Rhodopsins [PDF]
Current Protocols in Microbiology, 2016 AbstractIon‐pumping rhodopsins transfer ions across the microbial cell membrane in a light‐dependent fashion. As the rate of biochemical characterization of microbial rhodopsins begins to catch up to the rate of microbial rhodopsin identification in environmental and genomic sequence data sets, in vitro analysis of their light‐absorbing properties and ...
