PDB entry 2jbl (supersedes 4prc)

PHOTOSYNTHETIC REACTION CENTER FROM BLASTOCHLORIS VIRIDIS

The structure was published by Lancaster, C.R.D., Hunte, C., Kelley, J., Trumpower, B.L., and Ditchfield, R., in 2007 in a paper entitled "A Comparison of Stigmatellin Conformations, Free and Bound to the Photosynthetic Reaction Center and the Cytochrome Bc(1) Complex." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 2006.

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

This entry contains 32 copies of 4 unique biopolymers (complete list).
