cse, orf1, and their putative products are chimeric and may result from a duplication event. (A) Results from identity searches. Open arrows represent ORFs and indicate their reading directions, broken arrows indicate putative promoters, and hairpin loops symbolize putative rho-independent terminators. Hatched boxes represent repeat-containing regions, and grey color points out sequences from the cse and pcsB regions displaying high identity. Thick lines represent proteins, black boxes show putative signal peptides, and boxes with horizontal and oblique hatching symbolize putative LysM and CHAP domains, respectively. Homologous regions between proteins are linked, and positions of amino acids delimiting homologous regions are indicated. Identity (id.) and similarity (sim.) results are mentioned. (B) Duplication hypothesis. Grey and black arrows represent ORFs. Dashed lines both delimit the duplicated region and indicate the insertion site.
