SaPI operon I is required for SaPI packaging and is controlled by LexA

16 Jun 2007

Abstract excerpt

Transfer of Staphylococcus aureus pathogenicity islands (SaPIs) is directly controlled by the cellular repressor LexA. We have found that transcription of the SaPIbov1 operon I is repressed by LexA and is therefore SOS-induced. Two copies of the LexA binding site consensus (Cheo box) are present in the 5' region of this operon, at the same location in all of 15 different SaPIs analysed. Both of these boxes bind...
