It was concluded that a horizontal transfer of the photosynthesis gene cluster from an ancestral species belonging to the α subclass to that of the β subclass of purple bacteria had occurred and was followed by rearrangements of the operons in this cluster.

It is demonstrated that a hinge-shortened CPR variant, which favors an open conformation, makes a stable complex with heme–HO-1 and can support the HO reaction, although its efficiency is extremely limited.

The present data indicate that the plasticity of the nitrogenase-like enzyme caused the branched pathways of BChls a and b biosynthesis, ultimately leading to ecologically different niches of B Chl a- and b-based photosynthesis differentiated by more than 150 nm wavelength.

ESR signal of the iron-sulfur center F(X) and its function in the homodimeric reaction center of Heliobacterium modesticaldum.
The reactions of F(X) and quinone were discussed on the basis of the three-dimensional structural model of RC that predicts the conserved F( X)-binding site and the quin one-binding site, which is more hydrophilic than that in the photosystem I RC.

The gene named bciD, which encodes the enzyme involved in C7-formylation in bacteriochlorophyll e biosynthesis, was found and investigated by insertional inactivation in the brown-colored green…
Gene Expression System in Green Sulfur Bacteria by Conjugative Plasmid Transfer
The expression plasmid based on pDSK5191 was constructed by incorporating the upstream and downstream regions of the pscAB gene cluster on the C. tepidum genome, since these regions were considered to include a constitutive promoter and a ρ-independent terminator, respectively.

Changes in the structure and composition of the glycolipids that are dependent upon the temperature and period of cultivation are reported and the unique disaccharide RGDG was thought to be created by the site-specific transfer of an α-rhamnosyl group to MGDG(17:Cyc,16:0) after insertion of a methylene group into the precursor MGDg(16:1,16):0).
