The Bc(1) Complex of Rhodobacter Sphaeroides and Its Integration Into the Photosynthetic Chain
… and the role of isocyt $c\sb2$ in the photosynthetic chain were studied. Also the organization of the photosynthetic electron transfer chain of Rb. sphaeroides and the role of PufX were investigated. In Rb. sphaeroides, a bulky Val residue at position 209 in the $bc\sb1$ complex has …

Photosynthetic electron transport in cyanobacteria
… cyanobacteria and prochlorophytes have a similar photosynthetic apparatus. The light-driven reactions take place in the thylakoid membranes and three major membrane-intrinsic protein complexes carry out photosynthetic electron transfer, photosystem II, the cytochrome bf complex and photosystem I. …

The Effects Of Noncovalent Interactions Studied By Ultrafast Two-Dimensional Infrared Spectroscopy
… cofactor that plays an important role in photosynthetic electron transfer. Previous studies have shown that the local protein environment can tune the redox properties of phylloquinone; however, the exact mechanism and role of different noncovalent interactions in this process is not well …

Biochemical characterization of respiratory chain flavoproteins
Respiring organisms derive energy mainly from electron transfer reactions that are coupled to the translocation of ions across the cell membrane. This process is performed by a group of membrane-localized protein complexes that hold different cofactors with redox properties, such as flavins, hemes, …

Exploring the Function of Cytochrome c6A
The electron transfer protein cytochrome c6 (c6) of photosynthesis was believed to have been lost in plants until a ubiquitous and highly conserved homologue, named cytochrome c6A (c6A), was identified. Soon after its discovery, c6A was shown to be unable to replace c6 (or plastocyanin) …

The Ancestry and Function of Cytochrome c6A
… valve’, providing an alternative path for electron flow through the photosynthetic electron transport chain and thus alleviating reactive oxygen species production; that cytochrome c6A has a signalling role where it could sense high light stress and convey this signal to the nucleus to …
