Fig 3.

Assumed gene map of sea promoter regions in 21 S. aureus strains. P1 is the endogenous sea gene promoter, and P2 represents the latent promoter activated by phage induction in some sea₁ strains. The black arrow indicates the sea gene. Nucleotide sequence analysis of the sea promoter region was performed on the sequenced (whole genome) S. aureus strains MRSA252 (GenBank accession no. BX571856), MSSA476 (GenBank accession no. BX571857), Mu3 (GenBank accession no. AP009324), Mu50 (GenBank accession no. BA000017), MW2 (GenBank accession no. BA000033), and Newman (GenBank accession no. AP009315).
