PHOTOSYNTHETIC REACTION CENTER BLASTOCHLORIS VIRIDIS (ATCC)

The structure was published by Baxter, R.H., Ponomarenko, N., Srajer, V., Pahl, R., Moffat, K., and Norris, J.R., in 2004 in a paper entitled "Time-resolved crystallographic studies of light-induced structural changes in the photosynthetic reaction center." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.86 Å and deposited in 2003.

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

This entry contains 28 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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
