Function

[RCEH_RHOVI] The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis. [CYCR_RHOVI] The reaction center of purple bacteria contains a tightly bound cytochrome molecule which re-reduces the photo oxidized primary electron donor. [RCEM_RHOVI] The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis. [RCEL_RHOVI] The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis.

Publication Abstract from PubMed

Serial femtosecond crystallography is an X-ray free-electron-laser-based method with considerable potential to have an impact on challenging problems in structural biology. Here we present X-ray diffraction data recorded from microcrystals of the Blastochloris viridis photosynthetic reaction centre to 2.8 A resolution and determine its serial femtosecond crystallography structure to 3.5 A resolution. Although every microcrystal is exposed to a dose of 33 MGy, no signs of X-ray-induced radiation damage are visible in this integral membrane protein structure.
