Abstract: In order to explore DNA sites influenced by the trp repressor-operator interaction, bromodeoxyuridine (BrdU) was chemically incorporated into the TrpEDCBA, TrpR, and aroH operators at selected thymidine positions. Different patterns of repressor protection from strand scission in the two halves of complexes with the TrpEDCBA, TrpR, and aroH operators suggest different local environments despite the highly symmetric sequences. Although protection was observed at multiple sites in the operators in the presence o… Show more
