a Phylogenetic tree between the microbial rhodopsins and HeRs (68 rhodopsin sequences). Each function of rhodopsins is indicated using schematic ion-pumps and -channels in microbial rhodopsins and schematic regulatory function in HeRs. The HeRs belonging to the glutamine synthetase and photolyase groups are represented as orange and dark red circles, respectively. b OcHeR and other HeRs in the group of ABCT-containing operons are indicated using pink circles and stars, respectively. The direction of transcription of genes in the operons of the organisms is indicated by arrows. The predicted promoters are indicated using black bent arrows. Nucleotide gaps between the genes are labeled for each gene. EC extracellular side, CP cytoplasmic side, PPI protein‒protein interaction, hp hypothetical protein, duf domain unknown function.
