The crystal structure of the N-terminally acetylated BAH domain of Saccharomyces cerevisiae Sir3 bound to the nucleosome core particle reveals that the N-terminal acetylation stabilizes the interaction of Sir3 with the nucleosome. Additionally, we present a new method for the production of protein-nucleosome complexes for structural analysis. The N-terminal acetylation of Sir3 stabilizes its binding to the nucleosome core particle.,Arnaudo N, Fernandez IS, McLaughlin SH, Peak-Chew SY, Rhodes D, Martino F Nat Struct Mol Biol. 2013 Aug 11. doi: 10.1038/nsmb.2641.
