Promoter features that distinguish the two promoter classes. (A) Average values that correspond to transcription rate [20], gene expression level [20] and the turnover rate of H3 histone [26] are shown for SDN-enriched promoters (green) and SDN-less promoters (red). Values in each property were normalized (turnover rates were normalized among all promoters), such that their means are zero and standard deviations are one. (B) Average nucleosome profiles [7] are shown for SDN-enriched promoters (green), SDN-less promoters (red) and all promoters (blue). (C) Frequency of fuzzy nucleosomes [7] and nucleosomes with drastic positional changes (greater than 45 bp) before and after heat shock [9], as well as frequency of promoters with H2A.Z [11], is shown for SDN-enriched promoters (green), SDN-less promoters (red) and all promoters (blue). Error bars in A and C were calculated by bootstrapping.
