Purification and Reconstitution of an Integral Membrane Protein, the Photoreaction Center of Rhodobacter sphaeroides, Using Synthetic Sugar Esters

BioTechniques, 2000
Detergents are indispensable reagents for the extraction and solubilization of integral membrane proteins, but their removal from a reconstituted phospholipid-protein complex is usually desirable.

Antenna complexes protect Photosystem I from Photoinhibition

BMC Plant Biology, 2009
Background Photosystems are composed of two moieties, a reaction center and a peripheral antenna system. In photosynthetic eukaryotes the latter system is composed of proteins belonging to Lhc family. An increasing set of evidences demonstrated how these

Structure of the H subunit of the photosynthetic reaction center from the thermophilic purple sulfur bacterium, Thermochromatium tepidum [PDF]

European Journal of Biochemistry, 2001
The photosynthetic reaction center (RC) is a transmembrane protein complex that catalyzes light‐driven electron transport across the photosynthetic membrane. The complete amino‐acid sequence of the H subunit of the RC from a thermophilic purple sulfur bacterium, Thermochromatium tepidum, has been determined for the first time among purple sulfur ...

The loss of photosynthetic pathways in the plastid and nuclear genomes of the non-photosynthetic mycoheterotrophic eudicot Monotropa hypopitys

BMC Plant Biology, 2016
Background Chloroplasts of most plants are responsible for photosynthesis and contain a conserved set of about 110 genes that encode components of housekeeping gene expression machinery and photosynthesis-related functions. Heterotrophic plants obtaining

Direct and indirect electron transfer from cytochromes c and c₂ to the photosynthetic reaction center in pigment‐protein complexes isolated from Rhodocyclus gelatinosus

FEBS Letters, 1988
Electron transfer from soluble cytochromes c and c 2 to the photo‐oxidized bacteriochlorophyll dimer was studied in photosynthetic reaction center (RC) complexes and RC‐B870 complexes isolated from Rhodocyclus gelatinosus. In the RC‐B870 complex which consists of 6 polypeptides including a bound cytochrome subunit, cytochrome c from horse heart or ...

Mining Thermophile Photosynthesis Genes: A Synthetic Operon Expressing Chloroflexota Species Reaction Center Genes in Rhodobacter sphaeroides

Biomolecules
Photosynthesis is the foundation of the vast majority of life systems, and is therefore the most important bioenergetic process on earth. The greatest diversity of photosynthetic systems is found in microorganisms.
