From: Crystal structures of AztD provide mechanistic insights into direct zinc transfer between proteins
Structure of PdAztD. a and d Structure is shown as cartoon colored blue to red from N- to C-terminus, zinc ions, and disulfide bonded Cys residues are shown as spheres colored according to element. A channel calculated using MoleOnline73 is shown as gray surface. b, c, e, and f Zoomed in views of zinc-binding sites 1 and 2 with zinc shown as gray spheres at 0.5 VDW radius, side chains shown as sticks colored according to element and 2Fo–Fc density shown as blue mesh contoured at 1.0 σ b and e and anomalous difference density shown as orange mesh contoured at 5.0 σ c and f. Supplementary Table 4 lists occupancies, B-factors, and anomalous densities for all zinc sites in the asymmetric unit
