FIG. 1.
(A) Protein sequences of the SdiA epPCR variants. Amino acid changes are indicated by the black highlight. SdiA14C3 has a frameshift at N96 due to the deletion of one base pair. (B) Modeled protein structure of SdiA1E11. Truncated region (residues 153 to 171) is shown as a blue ribbon, and the mutations (F7L, F59L, Y70C, and M94K) are shown in red. WT indicates wild type.
