Structure 23 of 26 in a series of high pressure structures. Crystal was high pressure cryo-cooled at 4000 atmospheres in helium gas. Crystal temperature was maintained below 100 K prior to data collection at ambient pressure and 100 K. High pressure cryo-cooling procedure is described in secondary citation 1 (Kim et al., Acta Cryst. D61:881-890). Structure referred to as citrine4000_1 in primary citation (Barstow et al.). |

HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 2. This structure is refined slightly differently from the corresponding structure used for analysis in the primary citation (Barstow et al.). However, analysis of the deformation motion of the chromophore under pressure in this sequence of deposited structures produces an identical deformation trend. For copies of the structures as used in the analysis in the primary citation please contact the authors.
