FIG 3.

Identification of five transcription start sites in the rth cluster. Transcription start sites (TSSs) mapped by 5′ RLM-RACE are symbolized by broken arrows on the genetic map and are associated with promoter names. On the partial sequence extending from rv0634A to the 3′ end of hadA, the TSSs are shown (+1). The question marks indicate detected 5′-end RNAs that are unlikely to correspond to TSSs. Putative −10 boxes, proposed start codons, and tRNA-encoding gene sequences (thrT and metT) are underlined.
