Extended Data Fig. 13. UvrAB recruitment to the UV-damaged DNA strictly depends on local transcription, but not Mfd (compare to Fig. 5l,m).

Recruitment of UvrA (a) and UvrB (b) to the lacZ insulator (with or without promoter) was determined by ChIP-qPCR in Δmfd cell as in Fig. 5h. Results are shown as a fold change in the occupancy of UvrAB within the insulator of Δmfd cells following UV irradiation. **P < 0.01, ****P < 0.0001 (Student’s t test; equal variance).
