Heliorhodopsins show photocycles that are longer than one second, which is suggestive of light-sensory activity. Heliorhodopsin photocycles accompany retinal isomerization and proton transfer, as in type-1 and type-2 rhodopsins, but protons are never released from the protein [1].The structures of several heliorhodopsins have been solved displaying seven transmembrane helices (TM), six loops and short N and C termini [2,3]. Heliorhodopsins share a common fold with the type-1 rhodopsins, however there are clear structural differences, particularly within the loop regions and the large cavity in the cytoplasmic part of heliorhodpsin [2,3]. Heliorhodpsins are present in Archaea, Bacteria, Eukarya, and viruses [3].
