We explore the genome-wide occupancy of 4 different chromatin regulating complexes encoded in S. cerevisiae. We provide the data for histone acetyltransferases Gcn5 and Esa1 and histone deacetylases Hst1 and Rpd3/Sin3 under rich growth condition (YPD medium). We also include the occupancy data for RNA polymerase II under the same growth condition.
