spacer

80 microsecond laue diffraction snapshot from crystals of a photosynthetic reaction centre 3 millisecond following photoactivation.

The structure was published by Wohri, A.B., Katona, G., Johansson, L.C., et al., Davidsson, J., Groenhof, G., and Neutze, R., in 2010 in a paper entitled "Light-Induced Structural Changes in a Photosynthetic Reaction Center Caught by Laue Diffraction." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.0 Å and deposited in 2010.

The experimental data on which the structure is based was also deposited.

This entry contains 18 copies of 4 unique biopolymers (complete list).

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotetramers.
