How chromatin remodelers cooperate to organize nucleosomes around the start and end of genes is not known. We determined the genome-wide binding of remodeler complexes SWI/SNF, RSC, ISW1a, ISW1b, ISW2, and INO80 to individual nucleosomes in Saccharomyces, and determined their functional contributions to nucleosome positioning through deletion analysis. We applied ultra-high-resolution ChIP-exo mapping to Isw2 to determine its subnucleosomal orientation and organization on a genomic scale. Remodelers interacted with selected nucleosome positions relative to the start and end of genes and produced net directionality in moving nucleosomes either away or toward nucleosome-free regions at the 5' and 3' ends of genes. Isw2 possessed a subnucleosomal organization in accord with biochemical and crystallographic-based models that place its linker binding region within promoters and abutted against Reb1-bound locations. Together, these findings reveal a coordinated position-specific approach taken by remodelers to organize genic nucleosomes into arrays.CI - Copyright (c) 2012 Elsevier Inc. All rights reserved.
