Based on the result of PSI-BLAST search against GenBank Database, 38 microbial rhodopsin sequences were collected from archaea, eubacteria and eucarya. Two different phylogenetic methods were used to analyze their sequence alignment based on 7 transmembrane a-helice. The result of phylogenetic analysis shows that these microbial rhodopsins were divided into three clades.
