Crystal Structure of Photosystem I: a Photosynthetic Reaction Center and Core Antenna System from Cyanobacteria

The structure was published by Jordan, P., Fromme, P., Witt, H.T., Klukas, O., Saenger, W., and Krauss, N., in 2001 in a paper entitled "Three-dimensional Structure of Cyanobacterial Photosystem I at 2.5 A Resolution" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 2001.

The experimental data on which the structure is based was not deposited.

This entry contains 150 copies of 12 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 most likely quaternary structure is a 12meric assembly.


The are more than 5 unique protein polymers in this entry. More information is available on the Uniprot cross references page.
