Results of RNAPol-ChIP experiments. Schematic representation of the oxidoreductase-furA-katG region of M. smegmatis. The genes are indicated by boxes and the arrow corresponds to the furA promoter. The lines below the map correspond to different regions amplified by a pair of oligonucleotides. Fragment A: -689/-492; B: -81/91 (furA promoter); C: 374/557; D: 1155/1344. Below the lines, the values of the ratio of each fragment relative to the pfurA DNA.
