Acetylation of lysine residues at the H3 N-terminus is proposed to have a role in replication-coupled (RC) nucleosome assembly, a process critical for the inheritance of epigenetic information and maintenance of genome stability. However, the role of H3 N-terminal lysine acetylation and the corresponding lysine acetyltransferase (KAT) in RC nucleosome assembly are not known. Here we show that Gcn5, a KAT with a well-studied role in gene transcription, functions in parallel with Rtt109, the H3 lysine 56 KAT, to promote RC nucleosome assembly. Cells lacking both Gcn5 and Rtt109 are highly sensitive to DNA damaging agents. Moreover, cells lacking GCN5 or expressing an H3 mutant with mutations at the H3 N-terminus result in compromised deposition of new H3 onto replicating DNA and a reduction in the binding of H3 with CAF-1, a histone chaperone involved in RC nucleosome assembly. These results demonstrate that Gcn5 regulates RC nucleosome assembly, in part, through promoting the association of H3 with CAF-1 via H3 acetylation.
