(|F[photostationary]|
|F[dark]|) electron density map with PYP fold in the^ ground
state (white ribbon) and trans-chromophore (yellow) (right). The
density map (contoured at 3 ) shows an
excellent signal-to-noise^ ratio for the transient,
light-induced, structural changes. The^ largest signal is
localized at the active site (blue, positive; and red, negative
electron density). Figures 1 to 4 were made^ with AVS (28).
