FIG. 1.

Physical and genetic maps of lemA mutant L. monocytogenes strains. (A) Open reading frames found in wild-type L. monocytogenes 10403s; arrows indicate direction of transcription. The N-terminal amino acid sequence of LemA is shown below; the boxed region indicates the amino acids deleted in the ΔMIGWII mutant strain SD9-1. (B) N-terminal amino acid sequence of L. monocytogenes SD9-1 LemA. Underlined amino acids represent the SacI recognition site that replaced the 16 amino acids shown above in the wild-type sequence. (C) Physical map of the chromosomal deletion found in ΔlemA mutant L. monocytogenes NR1-1578.
