Photosynthetic reaction center/graphene bio-hybrid for low-power optoelectronics

Photosynthetica, 2023
Photosynthetic reaction center (pRC) purified from Rhodobacter sphaeroides 2.4.1 purple bacteria was deposited on a graphene carrier exfoliated from the liquid phase and layered on the surface of SiO2/Si substrate for optoelectronic application.

MONDE·T: A database and interactive webserver for non‐standard amino acids and peptide components in the PDB

Protein Science, Volume 35, Issue 11, November 2026.
Abstract Non‐standard amino acids (ncAAs) together with synthetic additions (like caps and linkers) are of wide interest for protein design and pharmaceutical optimization, as they can improve physicochemical properties and possibly reshape protein structure. Their inclusion in experimental structures has not been explored systematically.

Toward understanding the catalytic mechanism for two classes of bacterial phospholipid N‐methyltransferases

The FEBS Journal, Volume 293, Issue 20, Page 6253-6271, October 2026.
Phospholipid N‐methyltransferases (Pmts) synthesize phosphatidylcholine in many bacteria. In this study, we compared the catalytic mechanisms of two bacterial Pmt classes: the Rhodobacter (R‐) and the Sinorhizobium (S‐) type. Representative enzymes for each class were derived from Rubellimicrobium thermophilum and Agrobacterium tumefaciens ...

Involvement of transport in Rhodobacter sphaeroides chemotaxis

Journal of Bacteriology, 1987
The chemotactic response to a range of chemicals was investigated in the photosynthetic bacterium Rhodobacter sphaeroides, an organism known to lack conventional methyl-accepting sensory transduction proteins. Strong attractants included monocarboxylic acids and monovalent cations.

Modulation of Antioxidant Activity Enhances Photoautotrophic Cell Growth of Rhodobacter sphaeroides in Microbial Electrosynthesis

Energies, 2022
Global warming is currently accelerating due to an increase in greenhouse gas emissions by industrialization. Microbial electrosynthesis (MES) using electroactive autotrophic microorganisms has recently been reported as a method to reduce carbon dioxide,

Detection of Ring Structure and Its Flexibility in Periplasmic Region of FliL, Bacterial Flagellar Stator‐Associate Protein, in Marine Vibrio

Molecular Microbiology, Volume 126, Issue 4, Page 351-358, October 2026.
FliL, a single‐pass transmembrane flagellar protein with a large periplasmic domain, associates with the basal body and supports motor function under high‐load conditions (e.g., viscous environments). The periplasmic domain of deletion mutant FliL forms a flexible ring structure, likely reflecting the capacity of the full‐length protein to adaptively ...

Chromate reduction by Rhodobacter sphaeroides

Journal of Industrial Microbiology and Biotechnology, 2000
grew in the presence of up to 43 μM chromate and reduced hexavalent chromium to the trivalent form under both aerobic and anaerobic conditions. Reduced chromium remained in the external medium. Reductase activity was present in cells of R. sphaeroides independent of whether chromate was present or not in the growth medium.

Identification of the Rhodobacter sphaeroides SOS box [PDF]

Molecular Microbiology, 1998
Gel‐mobility shift assays with crude cell extracts of Rhodobacter sphaeroides, which belongs to the alpha group of the proteobacteria, have shown that a protein binds to the promoter of its recA gene, resulting in two retardation bands. Analysis of the minimal region of the R.
