FIG. 4.
Alignment of CirI with BacG (56), FtsX (6), and LolC and LolE (37). The consensus motif G-X9-F-X10-G for ortholog group 3-1 type ABC transporters is indicated. Predicted transmembrane domains are indicated in bold. The region constituting the predicted DUF214 domain is indicated by a line above the sequences. Identical residues are indicated by an asterisk, whereas colons and periods indicate conserved and semiconserved amino acid substitutions, respectively, according to the ClustalW grouping of amino acids. Gaps were introduced in the sequence to maximize alignment.
