N alpha-acetylated Sir3 stabilizes the conformation of a nucleosome-binding loop in the BAH domain.

PubMed Abstract: In Saccharomyces cerevisiae, acetylation of the Sir3 N terminus is important for transcriptional silencing. This covalent modification promotes the binding of the Sir3 BAH domain to the nucleosome, but a mechanistic understanding of this phenomenon is lacking. By X-ray crystallography, we show here that the acetylated N terminus of Sir3 does not interact with the nucleosome directly. Instead, it stabilizes a nucleosome-binding loop in the BAH domain.
