Figure 3 Conformational changes of the catalytic Gln11 and
Lys41. (a) Superposition of the two structures at pH* 5.2 (dark
grey) and 8.0 (light grey); only the most populated conformers
are shown for clarity. (b) Electron-density maps (3F[o] - 2F[c])
contoured at 1.7 for
the structures at pH* 5.2 and (c) at pH* 8.8. The figures were
generated using the program BOBSCRIPT (Esnouf, 1999[Esnouf, R.
M. (1999). Acta Cryst. D55, 938-940.]).
