Figure 3.

Stereo representations of the binding modes of BPPM A (a), BPPM B (b), and pTyr B (c). Contacts represented by dashed lines are distances less than 3.6 Å, except for certain interactions with aromatic rings. Interactions between the amide nitrogens of residues 216–221 and the phosphate groups of ligand A are too numerous to represent. [Diagrams were generated with the program o (16)].
