|However, with its low quantum yield (˂0.001), and comparatively slow switching kinetics, the photochromic properties of asFP595 are far from being optimal.
Recently, high-resolution crystal structures of wt asFP595 in its off state (Andresen et al., 2005; Willmann et al., 2005; Quillin et al., 2005), of the Ser158Val mutant in its on state, and of the Ala143Ser mutant in its on and off states (Andresen et al., 2005) were determined (fig 7).
|Currently, however, with its low quantum yield (< 0.1% and 7% before and after activation, respectively [8, 203]) and rather slow switching kinetics, the photochromic properties of asFP595 need to be improved. [...]
High-resolution crystal structures of wild-type (wt) asFP595 in its off state [205, 206, 207],
of the Ser158Val mutant in its on state, and of the Ala143Ser mutant in its on and off states 
were recently determined.
