 4-126 6.10e-66

Photosynthetic reaction center (RC) complex, subunit H; RC is an integral membrane protein-pigment complex which catalyzes light-induced reduction of ubiquinone to ubiquinol, generating a transmembrane electrochemical gradient of protons used to produce ATP by ATP synthase. Subunit H is positioned mainly in the cytoplasm with one transmembrane alpha helix. Provides proton transfer pathway (water channels) connecting the terminal quinone electron acceptor of RC, to the aqueous phase. Found in photosynthetic bacteria: alpha, beta, and gamma proteobacteria.

 4-126 3.65e-59

photosynthetic reaction center, subunit H, bacterial; This model describes the photosynthetic reaction center H subunit in non-oxygenic photosynthetic bacteria. The reaction center is an integral membrane pigment-protein that carries out light-driven electron transfer reactions. At the core of reaction center is a collection light-harvesting cofactors and closely associated polypeptides. The core protein complex is made of L, M and H subunits. The common cofactors include bacterichlorophyll, bacteriopheophytins, ubiquinone and no-heme ferrous iron. The net result of electron tranfer reactions is the establishment of proton electrochemical gradient and production of reducing equivalents in the form of NADH. Ultimately, the process results in the reduction of C02 to carbohydrates(C6H12O6) In non-oxygenic organisms, the electron donor is an organic acid rather than water. Much of our current functional understanding of photosynthesis comes from the structural determination and spectroscopic studies on the reaction center of Rhodobacter sphaeroides.
