X-Ray Structure of the Cytochrome-c(2)-Photosynthetic Reaction Center Electron Transfer Complex from Rhodobacter sphaeroides in Type II Co-Crystals

The structure was published by Axelrod, H.L., Abresch, E.C., Okamura, M.Y., Yeh, A.P., Rees, D.C., and Feher, G., in 2002 in a paper entitled "X-ray structure determination of the cytochrome c2: reaction center electron transfer complex from Rhodobacter sphaeroides." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 2002.

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

This entry contains 30 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.
