Chloroplast glycerolipid metabolism during maintenance and under stress

open access: yesThe Plant Journal, Volume 126, Issue 5, June 2026.
SUMMARY Chloroplasts are the defining organelles in green plant tissues, converting light into chemical energy with the help of an intricate and extensive membrane system, the thylakoids. In the process, they release oxygen and assimilate carbon and other elements into molecules that constitute a plant cell's building blocks.

Superoxide Generation by Chlorophyllide a Reductase of Rhodobacter sphaeroides [PDF]

open access: yesJournal of Biological Chemistry, 2008
Chlorophyllide a reductase of Rhodobacter sphaeroides, which were reconstituted with the purified subunits of BchX, BchY, and BchZ, reduced ring B of chlorophyllide a using NADH under anaerobic conditions. Interestingly, suppressor mutations rescuing the inability of R.

Phenotypic characterisation and genetic complementation of dimethylsulfoxide respiratory mutants of Rhodobacter sphaeroides and Rhodobacter capsulatus

open access: yes, 1995
Two chlorate resistant mutants of Rhodobacter sphaeroides were isolated which were deficient in dimethylsulfoxide reductase activity. Immunoblotting experiments showed that the phenotype of these mutants and that of Rhodobacter capsulatus strain DK9, a ...

Metabolic Regulation of Dimethylsulfoniopropionate Cleavage and Dimethyl Sulfide Production in Halomonas sp. D47

open access: yesAdvanced Science, Volume 13, Issue 23, 23 April 2026.
Dimethylsulfoniopropionate (DMSP) is a major marine organosulfur compound central to climate‐relevant dimethyl sulfide (DMS) production. In Halomonas sp. D47, DMSP catabolism is revealed to be coordinated by two transcriptional regulators, AcuR and AcuZ, which control gene expression by sensing DMSP and its metabolites.

A Rhodobacter sphaeroides Protein Mechanistically Similar to Escherichia coli DksA Regulates Photosynthetic Growth

open access: yesmBio, 2014
DksA is a global regulatory protein that, together with the alarmone ppGpp, is required for the “stringent response” to nutrient starvation in the gammaproteobacterium Escherichia coli and for more moderate shifts between growth conditions.

Engineered biosynthesis of bacteriochlorophyll b in Rhodobacter sphaeroides [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2014
Bacteriochlorophyll b has the most red-shifted absorbance maximum of all naturally occurring photopigments. It has a characteristic ethylidene group at the C8 position in place of the more common ethyl group, the product of a C8-vinyl reductase, which is carried by the majority of chlorophylls and bacteriochlorophylls used in photosynthesis.

Biomimetic Cell Membrane‐Coated MOFs System for Targeted Cancer Therapy

open access: yesAdvanced Science, Volume 13, Issue 21, 13 April 2026.
Biomimetic MOF‐based drug delivery nanoplatforms synthesized using liposomes or cell membranes as camouflage for multiple cancer therapeutics. ABSTRACT The integration of metal‐organic frameworks (MOFs) with cell membrane coatings has emerged as a revolutionary strategy to enhance the therapeutic efficacy of cancer nanomedicine.

The Lipoprotein and Peptidoglycan of Rhodobacter sphaeroides

open access: yesZeitschrift für Naturforschung C, 1989
The lipoprotein-peptidoglycan complex (rigid layer) from Rhodobacter sphaeroides was isolated. Treatment of the complex with N.O-diacetyl-muramidase cleaved off from the rigid layer the lipoprotein moiety with covalently bound peptidoglycan-fragments.
