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… Expand
Identification of protein W, the elusive sixth subunit of the Rhodopseudomonas palustris reaction center-light harvesting 1 core complex
TLDR
It is shown that a tagged version of protein W pulls down the RC-LH1 complex, a non-essential subunit of the Rhodopseudomonas Rps. Expand
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.

Cross-species investigation of the functions of the Rhodobacter PufX polypeptide and the composition of the RC-LH1 core complex.
TLDR
The present work established that dimeric RC-LH1 complexes can also be isolated from Rba. Expand
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). Expand
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. Expand
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. Expand

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
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.
