Energy transfer in ubiquitous rhodopsin pumps with xanthophyll antennas

The paper detects energy transfer from hydroxylated carotenoids to rhodopsin proton pumps in marine and freshwater bacteria.

Proton-transporting heliorhodopsins from marine giant viruses

This paper identifies a light-gated proton channel in a viral heliorhodopsin from Emiliania huxleyi virus 202, showing its potential role in host manipulation and optogenetic applications.

Characterization of heliorhodopsins detected via functional metagenomics in freshwater Actinobacteria, Chloroflexi and Archaea

This paper discovers and characterizes ten new heliorhodopsins from freshwater microbes using functional metagenomics, revealing their light absorption properties and potential roles in membrane lipid remodeling and oxidative stress.

Heliorhodopsins are absent in diderm (Gram-negative) bacteria: Some thoughts and possible implications for activity

The paper examines the presence of heliorhodopsins in diderm bacteria using metagenomic data and finds they are absent, suggesting a possible role in light-driven transport of amphiphilic molecules.

The use of a chimeric rhodopsin vector for the detection of new proteorhodopsins based on color

This paper describes a functional assay using a chimeric rhodopsin vector to detect proteorhodopsins without sequencing, enabling rapid visual results in marine microbiology courses.
