To understand the evolutionary relationship between triheme and tetraheme cytochrome subunits in the reaction center complex, genes located downstream of that coding for the M subunit of the reaction center complex (pufM) were amplified by PCR and analyzed in six established and two unidentified species of the genus Rhodovulum and five species of the genus Rhodobacter. All the Rhodovulum species tested had the pufC gene coding for the reaction-center-bound cytochrome subunit, while all the… 

Investigation of Rhodobacter capsulatus PufX interactions in the core complex of the photosynthetic apparatus

TLDR
The results indicate that in R. capsulatus PufX has the potential to be a central, homodimeric core complex component, and its cellular level is increased by interactions with the RC and LH1, consistent with a role of Puf X in core complex dimerization, as proposed for other Rhodobacter species.

Horizontal operon transfer, plasmids, and the evolution of photosynthesis in Rhodobacteraceae

TLDR
This work investigates the evolution of phototrophy in 105 genome-sequenced Rhodobacteraceae and provides the first unequivocal evidence for the horizontal transfer of the photosynthesis gene cluster (PGC).

Unusual features in the photosynthetic machinery of Halorhodospira halochloris DSM 1059 revealed by complete genome sequencing

TLDR
The genetic arrangement for this bacterium’s photosynthetic apparatus is of particular interest; its genome contains two sets of puf operons encoding the reaction center and core light-harvesting 1 (LH1) complexes having almost identical nucleotide sequences.

Evidence from the structure and function of cytochromes c2 that nonsulfur purple bacterial photosynthesis followed the evolution of oxygen respiration

TLDR
It is proposed that the involvement of C2 in nonsulfur purple bacterial photosynthesis was a metabolic feature subsequent to the evolution of oxygen respiration.

Function of a PscD Subunit in a Homodimeric Reaction Center Complex of the Photosynthetic Green Sulfur Bacterium Chlorobium tepidum Studied by Insertional Gene Inactivation

The PscD subunit in the homodimeric “type I” photosynthetic reaction center (RC) complex of the green sulfur bacterium Chlorobium tepidum was disrupted by insertional mutagenesis of its relevant pscD

A New Membrane-bound Cytochrome c Works as an Electron Donor to the Photosynthetic Reaction Center Complex in the Purple Bacterium, Rhodovulum sulfidophilum*

TLDR
It was concluded that either the membrane-bound cytochrome c2m or the water-soluble cyto chrome c2 work as a physiological electron carrier in the photosynthetic electron transfer pathway of Rvu.

A New Cytochrome Subunit Bound to the Photosynthetic Reaction Center in the Purple Bacterium, Rhodovulum sulfidophilum *

TLDR
The nucleotide sequence of the pufoperon, which contains the genes encoding the B870 light-harvesting protein and the reaction center complex of the purple photosynthetic bacterium, Rhodovulum sulfidophilum, was determined and it was revealed that this cytochrome contains only three possible heme-binding motifs; the tetraheme cy tochrome subunits was not present.

TLDR
Phylogenetic analysis of the light-harvesting proteins indicated that the LH1 α and β subunits of Rsp.

Mutational analyses of the photosynthetic reaction center-bound triheme cytochrome subunit and cytochrome c2 in the purple bacterium Rhodovulum sulfidophilum.

TLDR
It is shown that newly isolated soluble cytochrome c-549 with a redox midpoint potential of +238 mV reduced the photooxidized cy tochrome subunit in vitro, suggesting that c-550 mediates the cyto Chrome c(2)-independent electron transfer from the bc(1) complex to the RC-bound cyto chrome subunit.

Evolutionary Relationships between Reaction Center Complexes with and without Cytochrome c Subunits in Purple Bacteria

TLDR
The major difference between the two types of RC is only in the presence or absence of the cytochrome subunit and the structure of the other three peptides with pigments and quinones is similar to each other.

Intrageneric Structure of the Genus Rhodobacter: Transfer of Rhodobacter sulfidophilus and Related Marine Species to the Genus Rhodovulum gen. nov.

TLDR
With few exceptions, the marine Rhodobacter species can be differentiated phenotypically from the freshwater species on the basis of salt requirement for optimal growth, sulfide tolerance, final oxidation product of sulfide, and polar lipid composition and it is proposed that all marine RhodOBacter species should be transferred to the genus Rhodovulum gen. nov.

Interaction site for soluble cytochromes on the tetraheme cytochrome subunit bound to the bacterial photosynthetic reaction center mapped by site-directed mutagenesis.

TLDR
Results indicate that the cluster of acidic residues immediately surrounding the distal heme 1 of the RC-bound tetraheme subunit forms an electrostatically favorable binding site for soluble cytochromes.
