Chromatin remodelers have been implicated in the regulation of histone-modifying complexes. However, the underlying mechanism remains poorly understood. The Rpd3S histone deacetylase complex is recruited by elongating RNA polymerase II to remove histone acetylation at coding regions in a manner that is dependent on methylation of lysine 36 on histone 3 (H3K36me), and Rpd3S prefers dinucleosomes. Here, we show that the binding of Rpd3S to dinucleosomes and its catalytic activity are sensitive to the length of nucleosomal linker in a nonlinear fashion. Intriguingly, we found that H3K36me on one nucleosome stimulates Rpd3S to deacetylate the neighboring nucleosomes when those two nucleosomes are within an optimal distance. Finally, we demonstrate that chromatin remodelers enhance Rpd3S activity by altering nucleosomal spacing, suggesting that chromatin remodelers prime chromatin configuration to fine-tune subsequent histone modification reactions. This mechanism is important for accurate temporal control of chromatin dynamics during the transcription elongation cycle.
