H4 tail recognition by Orc1 and Sir3 BAH domains. a Electrostatic surface potential representation of Orc1 in complex with the nucleosome (positive, blue; negative, red). Histone H4 tail, green. b Electrostatic surface potential representation of Sir3 BAH in complex with the nucleosome (PDB ID: 4KUD). Histone H4 tail, gray. c Overview of H4 tail interface highlighting the secondary structure elements in histones and in Orc1. d Detailed view of superimposed pockets of Orc1 BAH domain (purple) and Sir3 BAH domain (orange) from the respective nucleosome complex structures. H4 tail in Orc1 structure (green) and in Sir3 structure (gray). Residues that make important contacts are depicted as sticks
