Figure 3.
Structural comparison of OiMacroD with different macrodomains. OiMacroD-ADPr structure (grey) is superimposed with the crystal structure (green) of (a) human MacroD2 (PDB 4IQY), (b) EcYmdb macrodomain (PDB 1SPV), (c) hypothetical protein Af1521 from A. fulgidus (PDB 2BFQ) and (d) Chikungunya virus macrodomain (PDB 3GPO). The ADPr molecule bound to OiMacroD is shown (orange) superposed to the ligand present in each homologue (yellow). Water molecules are represented as orange (OiMacroD) or cyan (superposed macrodomain) spheres. The interactions established by each structural water molecule are represented as dashed lines in grey (OiMacroD) or red (superposed macrodomain).
