FIG. 1.

Schematic representation of gene organization in prophage MuMenB of N. meningitidis strain MC58. For each gene, arrows indicate the direction of transcription and are scaled according to gene length. Numbers above arrows correspond to TIGR annotation (the suffix NMB has been omitted for simplicity in all cases). Newly annotated ORFs are marked NB1 to NB5 (for new in serogroup B). Putative functional assignments and correspondences to Mu homologues are reported below the arrows. Hypothetical sources of genes are color coded as indicated below the map. Hatched colored arrows represent genes for which source assignment may fall into two categories.
