		+	== Publication Abstract from PubMed ==
		+	The acetylation of lysine 56 of histone H3 (H3K56ac) enhances the binding affinity of histone chaperones to H3-H4 dimers. CREB binding protein (CBP) possesses a bromodomain that recognizes H3K56 acetylation. CBP also possesses a histone acetyltransferase (HAT) domain, which has been shown to promote H3K56 acetylation of free histones to facilitate delivery of replication-dependent chaperones to acetylated histones for chromatin assembly. However, the mechanism by which the CBP bromodomain recognizes H3K56ac, and thecontext in which such recognition occurs remains elusive. Here, we solved the crystal structure of the CBP bromodomain in complex with an H3K56ac peptide. Our data demonstrate that the CBP bromodomain recognizes H3K56ac with high affinity. Structural and affinity analyses reveal that the CBPbromodomain prefers an aromatic residue at the -2 position and an arginine at the -4 position from the acetyl-lysine, and that the CBP bromodomain selectively recognizes an extended conformation of the H3 alphaN helix that contains H3K56ac. We also demonstrate that the CBP bromodomain binds to H3K56ac in a recombinant H3-H4 dimer but not in a mono-nucleosome. Our results suggest that the CBP bromodomain selectively recognizes an extended conformation of the K56-acetylated H3 alphaN region within an H3-H4 dimer, which is expected to facilitate the HAT activity of CBP for subsequent H3K56 acetylation of free histones.
