Streptavidin association with H2A N-tail domains does not inhibit RSC remodeling-dependent nucleosome DNA site exposure. (A). Detection of RSC remodeling-dependent exposure of the HhaI cognate DNA site at the nucleosome dyad, which can be uncoupled to mobilization (35). (B). Experimental timeline. HhaI and RSC were added at t = 0 and t = 6 min., respectively. Samples of the digest were taken at the times indicated by the black arrows below the line. (C, D). Products of digestion were run on 5% SDS PAGE gels and quantified by phosphorimagery. (D). Plot of average percent uncut vs time (min). Streptavidin bound and unbound samples are indicated by the open and filled squares, respectively (n = 3, avg. SD 4%).
