Schematic representation of the genomic regions containing STM3602, STM3846, and retron St-85. (A) Schematic diagram of the region surrounding STM3602. (B) Schematic diagram of the region surrounding STM3846. This gene is located on a 2.13-kb retron at position 4,051,144 on the chromosome between STM3844, a pseudogene encoding an integrase with a truncation at amino acid residue 164, and yidY, encoding a putative multidrug efflux system protein. The orientations of the msr and msd genes are indicated by the arrows. This figure was constructed using coliBASE (86) and data from the study by Ahmed and Shimamoto (56).
