k3-weighted EXAFS (top panels) and modulus of phase-corrected Fourier transform (bottom panels) of experimental values (solid lines) and simulations (dashed lines, parameters in Table 5) of the N-terminal part of HIV-2 integrase-2 with (a) and without (b) β-mercaptoethanol. Insets of bottom panels: final geometry of imidazole ring after refinement, with Zn as the central atom, N atoms (1) and (4), and C atoms (2), (3) and (5). |
