Figure 5.
Interaction between (Nδ1)H247-BeF[3]^− and the neighboring residues (cross-eye stereo representation). The structure of one monomer is in yellow, the other is in cyan, PRPP·BzAM is in black, Be is in lemon, and F is in light blue. Blue dashed lines represent Mg^2+ interactions with PRPP and BeF[3]^−, olive dashed lines represent interatomic distances L[1], L[2], and L[3] and green dashed lines represent distances d[1], d[2], d[3], and d[4] as summarized in Table 1. Produced with PyMol v 1.1.
