Cardiolipin increases in chromatophores isolated from Rhodobacter sphaeroides after osmotic stress: structural and functional roles

open access: yesJournal of Lipid Research, 2009
Chromatophores isolated from cells of Rhodobacter sphaeroides exposed to hypertonic solutions were enriched in cardiolipin (CL). Because CL levels are raised by increasing the incubation time of R.

Synthetic Cells on Demand: From Molecular Stimuli to Cellular Functions

open access: yesChemSystemsChem, Volume 8, Issue 2, March 2026.
ABSTRACT Synthetic cells constructed via bottom‐up approaches using lipid or polymer vesicles have become essential tools for mimicking cellular functions and studying synthetic biological systems. These vesicles can undergo morphological changes and trigger internal reactions in response to external stimuli, such as osmotic pressure, temperature, pH ...

eMap 2.0: A Web‐Based Platform for Identifying electron Transfer Pathways in Proteins and Protein Families

open access: yesWIREs Computational Molecular Science, Volume 16, Issue 2, March/April 2026.
In this review, we present eMap 2.0, a web‐based platform for analyzing electron transfer pathways in proteins. We highlight representative applications of eMap, including its use in characterizing electron transfer within individual proteins and in revealing shared electron transfer pathways across protein families.

Photosynthetic apparatus of Rhodobacter sphaeroides exhibits prolonged charge storage

open access: yesNature Communications, 2019
Photosynthetic proteins are used to harvest solar energy in bio-photovoltaics, but are typically not investigated for charge storage. Here the authors report prolonged charge storage in multilayers of photoproteins as well as a proof-of-principle ...

The bacterial RNA polymerase-associated CarD protein couples promoter activity to DNA supercoiling

open access: yesNature Communications
RNA polymerase (RNAP) must unwind duplex DNA prior to transcription initiation. In bacteria, unwinding starts at a DNA motif called the promoter −10 element. Specifically, non-template strand bases interact with RNAP to trigger the process.

B-side Electron Transfer in Bacterial Photosynthetic Reaction Centers Revealed by a Few-Cycle Pulse Laser

open access: yesEPJ Web of Conferences, 2013
B-side electron transfer in wide-type reaction centers from Rhodobacter sphaeroides 2.4.1 was investigated by broadband real-time vibrational spectroscopy.

Role of the Irr protein in the regulation of iron metabolism in Rhodobacter sphaeroides.

open access: yesPLoS ONE, 2012
In Rhizobia the Irr protein is an important regulator for iron-dependent gene expression. We studied the role of the Irr homolog RSP_3179 in the photosynthetic alpha-proteobacterium Rhodobacter sphaeroides.

Macromolecular crowding in Rhodobacter sphaeroides

open access: yes, 2020
Macromolecular crowding is thought to have an important role in protein dynamics and molecular diffusion in bacteria. However, the dynamic and heterogeneous nature of the cytoplasm makes it challenging to study and test the significance of crowding in live cells. Previous studies have used diffusion coefficient of protein to estimate excluded volume in

Complexity in Rhodobacter sphaeroides chemotaxis

open access: yes, 2017
Perceiving and responding to the environment is key to survival. Using the prokaryotic equivalent of a nervous system – the chemotaxis system – bacteria sense chemical stimuli and respond by adjusting their movement accordingly. In chemotactic bacteria, such as the well-studied E.
