Fig. 2: Structure of AsfvAP/DNA-1 complex.
From: A unique DNA-binding mode of African swine fever virus AP endonuclease
a Cartoon view showing the overall fold of AsfvAP/DNA-1 complex. α-helices, β-strands and loops of AsfvAP are colored in cyan, purple, and pink, respectively. The uncleaved strand, the upstream and downstream of the product strand of DNA-1 are colored in red, blue and yellow, respectively. b Conformations of the active site residues and nucleotides. 2Fo–Fc electron density map was contoured at 1.5 sigma level. c Detailed coordination of the Zn2+ ions. The Zn2+ ions are shown as spheres in black in all panels.
