FIG. 4.

Region 3 and the Pnm1 prophage. Details are as given in Fig. 2. The numbers 1 to 52 above the ORFs indicate genes rth1 to rth52. The transcription orientation is from left to right for rth2 to rth52. Dark gray ORFs are homologous to both phage genes and to clustered genes in H. influenzae. ORFs shaded in light gray are only homologous to clustered genes in H. influenzae. ORFs in hatched boxes are only homologous to phage proteins (rth17, rth40, and rth43). Blocks of ORFs that yielded identical results in dot blot analysis are delineated by paired vertical lines above the map. +/−, positive result with one of two strains of N. lactamica.
