The NuA4 complex is also involved in DNA repair. Involved in cell cycle progression and meiosis. [ESA1_YEAST] Catalytic component of the NuA4 histone acetyltransferase (HAT) complex which is involved in epigenetic transcriptional activation of selected genes principally by acetylation of nucleosomal histones H4, H3, H2B, H2A and H2A variant H2A.Z. Acetylates histone H4 to form H4K5ac, H4K8ac, H4K12ac and H4K16ac, histone H3 to form H3K14ac, histone H2B to form H2BK16ac, histone H2A to form H2AK4ac and H2AK7ac, and histone variant H2A.Z to form H2A.ZK14ac. Acetylation of histone H4 is essential for DNA double-strand break repair through homologous recombination. Involved in cell cycle progression. Recruitment to promoters depends on H3K4me. [EPL1_YEAST] Component of the NuA4 histone acetyltransferase complex which is involved in transcriptional activation of selected genes principally by acetylation of nucleosomal histone H4 and H2A. The NuA4 complex is also involved in DNA repair. Involved in gene silencing by neighboring heterochromatin, blockage of the silencing spreading along the chromosome, and required for cell cycle progression through G2/M. [EAF6_YEAST] Component of the NuA4 histone acetyltransferase complex which is involved in transcriptional activation of selected genes principally by acetylation of nucleosomal histone H4 and H2A. The NuA4 complex is also involved in DNA repair. Component of the NuA3 histone acetyltransferase complex, that acetylates Lys-14 of histone H3. Recruitment of NuA3 to nucleosomes requires methylated histone H3. In conjunction with the FACT complex, NuA3 may be involved in transcriptional regulation. Publication Abstract from PubMed NuA4 catalyzes the acetylation of nucleosomes at histone H4, which is a well-established epigenetic event, controlling many genomic processes in Saccharomyces cerevisiae. Here we report the crystal structures of the NuA4 core complex and a cryoelectron microscopy structure with the nucleosome. The structures show that the histone-binding pocket of the enzyme is rearranged, suggesting its activation. The enzyme binds the histone tail mainly through the target lysine residue, with a preference for a small residue at the -1 position. The complex engages the nucleosome at the dish face and orients its catalytic pocket close to the H4 tail to achieve selective acetylation. The combined data reveal a space-sequence double recognition mechanism of the histone tails by a modifying enzyme in the context of the nucleosome.
