The proteorhodopsins genes were found even in Antarctic Sea ice samples (moderate UV areas) and in Modern Stromatolites living a High-Altitude Andean Lake in Argentinean Puna in the extreme UV irradiation areas. According to the data of modelling rhodopsin named HbR1 may bind carotenoids. Its gene was found trough bioinformatics research in the genome of the Antarctic UV resistant bacteria Hymenobacter sp. PAMC 26554. HbR1 gene was expressed in E. coli for the study of the physical and chemical properties of the purified protein.
