Permanganate footprints
WebMay 18, 2010 · Fast footprinting reveals that thymines at positions from -11 to +2 in I 2 are permanganate-reactive, demonstrating that RNAP opens the entire initiation bubble in the … WebJun 6, 2013 · The most widely accepted assay for monitoring the position of Pol II along DNA once it has melted the DNA (the Pol II “bubble”) is permanganate footprinting, which detects unpaired T residues in single-stranded open complexes ( Adelman and Lis, 2012 ).

Numbers in black indicate … WebMar 5, 2010 · However, the permanganate footprints suggest that low (nonrepressing; Fig. 4 A) concentrations of CRP Mt or CRP Mt-cAMP do not significantly enhance open complex formation at the whiB1 promoter compared with reactions lacking CRP Mt (Fig. 5 A) indicating that a step after open complex formation is activated. Further experimental …
WebPotassium permanganate footprints indicate that following recruitment, RNAP facilitates unwinding of DNA at the -10 hexamer of T3SS promoters. Transcriptional activators generally recruit RNAP by contacting the α or σ 70 subunits (or both). I have found that ExsA recruits RNAP to the P exsC and P exsD promoters by contacting region 4.2 of σ 70. WebNov 11, 2007 · Finally, we used permanganate footprint assays as an independent method to confirm stalled Pol II at selected genes 5, 14. For example, the rho gene displays clear permanganate sensitivity downstream of the transcription start site (+36 bp), consistent with the Pol II stalling profile seen in Toll10b mutants ( Fig. 3D; see Fig. 1B ).
WebAug 28, 2009 · Potassium permanganate footprints indicate that ExsA functions at the level of transcription initiation, but this method cannot discern whether ExsA recruits RNAP and/or promotes isomerization to the open complex. The abortive initiation assay, however, can be used to estimate the isomerization rate constant and overall reaction rate for a ... WebRNA Polymerase Stalling at Developmental ... - Young Lab - MIT
WebThis footprint is significantly different from that obtained with unmodified polymerase, starting upstream of around position −20. Previous work has indicated that the T4 AsiA protein, which binds tightly to s70, is the phage modification required for MotA activation.
