[https://www.uniprot.org/uniprot/RT109_YEAST RT109_YEAST] Required for acetylation of 'Lys-56' of histone H3 (H3K56ac) which occurs in S phase and disappears during G(2)/M phase of the cell cycle and is involved in transcription DNA repair process. H3K56 acetylation weakens of the interaction between the histone core and the surrounding DNA in the nucleosomal particle and drives chromatin disassembly. Involved in regulation of Ty1 transposition.<ref>PMID:11779788</ref> <ref>PMID:17046836</ref> <ref>PMID:17369253</ref> <ref>PMID:17690098</ref> <ref>PMID:17320445</ref> <ref>PMID:17272722</ref> <ref>PMID:17272723</ref> <ref>PMID:18577595</ref> <ref>PMID:18723682</ref>

== Publication Abstract from PubMed ==

Histone acetylation plays important roles for the regulation of many fundamental cellular processes. Saccharomyces cerevisiae Rtt109 is an important class of histone acetyltransferases (HATs), which promote genome stability by directly acetylating newly synthesized histone H3 lysine 56 (H3-K56) through an unknown mechanism. Here, we report the crystal structures of Rtt109 at 2.2 A and Rtt109/Acetyl-CoA binary complex at 1.9 A. The structure displays a vise-like topology with mixed three-layered alpha/beta module forming the central module, whose core region resembles the structure of GCN5 HAT domain and P300/CBP HAT domain. Using structural and biochemical analyses, we have discovered the catalytic active site and have identified Asp288 as the deprotonation residue and Lys290 as the autoacetylation residue. We have further proposed the unique H3-K56 anchoring pocket and the potential H3alphaN binding groove. Our work has provided structural insights to understand the acetylation mechanism of H3-K56 by Rtt109.
