PHOTOSYNTHETIC REACTION CENTER FROM BLASTOCHLORIS VIRIDIS

Structural highlights

2jbl is a 4 chain structure with sequence from Blastochloris viridis. This structure supersedes the now removed PDB entry 4prc. The September 2011 RCSB PDB Molecule of the Month feature on O-GlcNAc Transferase by David Goodsell is 10.2210/rcsb_pdb/mom_2011_9. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

[RCEM_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. [RCEL_RHOVI] The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis. [RCEH_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

We describe in detail the conformations of the inhibitor stigmatellin in its free form and bound to the ubiquinone-reducing (Q(B)) site of the reaction center and to the ubiquinol-oxidizing (Q(o)) site of the cytochrome bc(1) complex. We present here the first structures of a stereochemically correct stigmatellin in complexes with a bacterial reaction center and the yeast cytochrome bc1 complex. The conformations of the inhibitor bound to the two enzymes are not the same. We focus on the orientations of the stigmatellin side-chain relative to the chromone head group, and on the interaction of the stigmatellin side-chain with these membrane protein complexes. The different conformations of stigmatellin found illustrate the structural variability of the Q sites, which are affected by the same inhibitor. The free rotation about the chi1 dihedral angle is an essential factor for allowing stigmatellin to bind in both the reaction center and the cytochrome bc1 pocket.

A comparison of stigmatellin conformations, free and bound to the photosynthetic reaction center and the cytochrome bc1 complex.,Lancaster CR, Hunte C, Kelley J 3rd, Trumpower BL, Ditchfield R J Mol Biol. 2007 Apr 20;368(1):197-208. Epub 2007 Feb 11. PMID:17337272^[1]
