Production of Eukaryotic Heliorhodopsins for Structural Analysis Utilizing the LEXSY Expression System / D.Kornilov, A.Vlasov, [a.o.] // International Journal of Biological Macromolecules [Electronic resource]. – 2024. – Vol. 283, Pt. 1. – P. 137324. – URL: https://doi.org/10.1016/j.ijbiomac.2024.137324. – Bibliogr.: 60.

Heliorhodopsins (HeRs) constitute a novel and distinct group of microbial rhodopsins, characterized by the inverted position of C- and N- termini relative to conventional Type I rhodopsins. The production of HeRs for structural and functional investigations has proven challenging, as evidenced by the structural elucidation of only two proteins and the functional characterization of a few others to date. Notably, no eukaryotic HeRs have been reported thus far. In this study, we report the first expression of three eukaryotic HeRs in the LEXSY expression system: from marine and freshwater algae and a free-living marine unicellular eukaryote. We spectroscopically characterized these HeRs, demonstrating that they were expressed in the functional states. Finally, we report their successful crystallization, thus paving the way for their further structural and functional studies.
