Figure 2.

Genomic organization of rsa genes in the S. aureus N315 strain. Red arrows denote the rsa transcripts and their orientations, and the blacks arrows are for the flanking open reading frames (ORFs). The genes are represented to scale. The sizes of the rsa genes were determined based on the experimental determination of the 5′ start by RACE mapping and primer extension, estimates from denaturing gel electrophoresis, and the presence of transcription terminator. For RsaJ, the transcription start site was not determined and the length is estimated. RsaB and RsaF do not contain transcription terminator at their 3′-ends. In Table 1, the exact genomic location of rsa genes is given.
