Transcriptional fusion assays and the SMc00261 operon. (A) GusA activities were measured for fusions in genes SMc00262 and SMc00261 in wild-type (Rm1021) and chvI261 mutant (SmUW38) strain backgrounds. (B) In the operon diagram, F1 and F2 represent the position of the fusions to SMc00262 and SMc00261 respectively. The grey box (B) represents the region for ChvI binding, and P1, P2 and P3 are predicted promoters.
