First, adding an acetyl moiety to the ε-amino group neutralizes the posi-tive charge. The already bulky lysine side chain becomes bulkier. Since histone proteins are highly basic and can interact extensively with the negatively charged DNA, acetylation may weaken histone-DNA interactions, hence lehigh valley mfmWebbThis promotes DNA unfolding and chromatin decondensation that facilitates transcription and protein synthesis. Histone deacetylases remove the acetyl groups from histones. This leads to formation of the transcriptionally inactive heterochromatin, in which gene expression is hindered. lehigh valley model trains
