Examples of newly discovered pseudogenes in the S. flexneri 2a genome and their counterparts in E. coli MG1655. (A) Pseudogene formed by integration of an IS element. (B) Nonsense mutation (star) in the S. flexneri homolog of E. coli b2107 forming a truncated CDS (annotated as yohN). (C) Frameshift mutation in the S. flexneri homolog of the E. coli hyfG gene, which resulted in the incorrect annotation of two CDSs in Shigella.
