Epigenetics describes heritable traits that are not linked to changes in DNA sequence, but to chemical reactions that regulate the transcription of the genes. A common event is methylation of lysine residues on histone proteins, which results in regulation of gene expression. Which reaction energy coordinate would be consistent for the mechanism for the exergonic SN2 reaction shown below?
