Energetic Basis of Microbial Growth and Persistence in Desert Ecosystems

mSystems, 2020
Microbial life is surprisingly abundant and diverse in global desert ecosystems. In these environments, microorganisms endure a multitude of physicochemical stresses, including low water potential, carbon and nitrogen starvation, and extreme temperatures.

Comparative analysis of canonical and noncanonical rhodopsins in Amphidinium carterae and Karlodinium veneficum

Journal of Phycology, Volume 62, Issue 2, Page 360-376, April 2026.
Abstract Rhodopsins are ancient and versatile light‐sensitive proteins, widely distributed across microbial life. In dinoflagellates, however, their diversity and function remain poorly understood, owing to the lineage's extreme genomic divergence. Here, we surveyed the rhodopsin complements of two dinoflagellates, Amphidinium carterae and Karlodinium ...

Microbial Rhodopsins: Structural–Functional Mechanisms and the Design of Optogenetic Silencing Tools—With Emphasis on Halorubrum Archaeorhodopsins

Biology
Microbial rhodopsins are light-sensitive membrane proteins that use retinal as a covalent chromophore and adopt a seven-transmembrane α-helical fold. They are widely distributed across archaea, bacteria, algae, and fungi and mediate diverse functions ...

Rhodopsin from Haloquadratum walsbyi is a light-driven magnesium transporter

Nature Communications
The functionally unknown Middle rhodopsin (HwMR) is a microbial rhodopsin (mRho) identified in Haloquadratum walsbyi, an archaeon that thrives in a 2 M MgCl2 environment harmful to most other microorganisms.

Rhodopsin 7–The unusual Rhodopsin in Drosophila [PDF]

, 2016
Rhodopsins are the major photopigments in the fruit fly Drosophila melanogaster. Drosophila express six well-characterized Rhodopsins (Rh1–Rh6) with distinct absorption maxima and expression pattern.

Proton motive force generated by microbial rhodopsin promotes extracellular electron transfer

Synthetic and Systems Biotechnology
The primary limitation to the practicability of electroactive microorganisms in bioelectrochemical systems lies in their low extracellular electron transfer (EET) efficiency.

Probing how initial retinal configuration controls photochemical dynamics in retinal proteins

EPJ Web of Conferences, 2013
The effects of the initial retinal configuration and the active isomerization coordinate on the photochemistry of retinal proteins (RPs) are assessed by comparing photochemical dynamics of two stable retinal ground state configurations (all-trans,15-anti

Mutation-independent treatment of autosomal dominant Retinitis Pigmentosa (adRP) [PDF]

, 2010
Viral-mediated gene therapy holds great promise for the treatment of severe inherited retinal diseases, such as Retintitis Pigmentosa (RP), which is caused by mutations in genes preferentially expressed in photoreceptor cells. The availability of vectors

Time-resolved FTIR study of light-driven sodium pump rhodopsins

, 2018
Light-driven sodium ion pump rhodopsin (NaR) is a new functional class of microbial rhodopsin. Present step-scan time-resolved FTIR spectroscopy revealed that the K, L and O intermediates of NaRs contain 13-cis retinal with similar distortion.

Photochromism of Anabaena Sensory Rhodopsin

, 2016
Protein-controlled photochemical reactions often mediate biological light-signal and light-energy conversions. Microbial rhodopsins possess all-trans or 13-cis retinal as the chromophore in the dark, and in the light-driven proton pump, bacteriorhodopsin
