Figure 6. Refined structure of the active site region of HPPK
superimposed with the MAD electron density at 2.6 Å
resolution contoured at (a) 1.5σ and (b) the final 2 F[o] −
F[c] map at 2.1 Å contoured at 1σ. The protein, inhibitor
and sulfate ion is represented in red, green or blue,
respectively. Water molecules are shown by small spheres. The
Figure was produces with the program MOLOC [Gerber 1992].
