Fig. 1From: Localization and dimer stability of a newly identified microbial rhodopsin from a polar, non-motile green algaeComparative sequence analysis of the CsR with other proton-pumping rhodopsins. The green and purple background depicts the identical and similar residues, respectively. Black bar below alignment depicts the predicted transmembrane regions. The red star depicts the conserved lysine residue and #depicts the conserved proton transport pathway of the CsRBack to article page
