Figure 1.
Figure 1 An omit difference electron-density map for Glu118 calculated with coefficients (F[o] - F[c]) and contoured at 3 (magenta) revealing the hydrogen-bonding (yellow dashed lines) pattern that defines the side-chain properties. F[o] and F[c] represent the observed and calculated structure factors, respectively. The refined model is shown in sticks with O atoms in red, N atoms in blue and C atoms in white. All figures were prepared using PyMOL (DeLano, 2002[DeLano, W. L. (2002). The PyMOL Molecular Graphics System. DeLano Scientific, San Carlos, CA, USA.]).
