Summary: The study utilizes a dual-laser 2DES technique to investigate the electronic energy transfer process in bacterial light-harvesting complexes. Through principal component analysis, it is found that the energy transfer is modulated by a low-frequency vibrational mode of the exciton donor.

Summary: CO2 can be converted into organic acids and carotenoids by photoautotrophic bacteria in the MES reactor. Introducing cobalt-phosphate-assisted water oxidation at the anode can improve the performance of MES.

Summary: Phospholipid-protein interactions are important for photosynthetic membranes. This study characterizes the phospholipid composition of intracytoplasmic membranes (ICM) from genetically altered Rhodobacter sphaeroides strains and finds selective interactions between the complexes and specific phospholipids. Expression of different light-harvesting (LH) complexes alters the phospholipid composition, and purified LH1-reaction center core complexes have different phospholipid compositions. The study also investigates the effects of carotenoids on phospholipid composition.

Summary: The study investigated the effects of low-molecular-weight polyols on the optical and triplet excitation dynamics of the light-harvesting complex 2 (LH2) from Rhodobacter (Rba.) sphaeroides. The results showed that the presence of glycerol and sorbitol influenced the conformations of carotenoids and the absorption intensity of bacteriochlorophyll a. Additionally, the sensitivity of Rba. sphaeroides LH2 to low-molecular-weight polyols was found to be higher compared to the thermophiles purple bacterium Thermochromatium (Tch.) tepidum.

Summary: This study explores the interplay between the arrangement of light-harvesting antennae and the efficiency of exciton transport in purple bacterial photosynthesis. The results show that arrangements with aggregated LH1s have a higher efficiency than arrangements with randomly distributed LH1s in a wide range of physiological light fluences. This effect is suggested to be an adaptive strategy toward solar light fluence across different purple bacterial species.

Summary: Lesions to DNA can threaten cell survival by compromising chromosome integrity, and the bacterial SOS response is a common transcriptional regulatory mechanism to address DNA damage. A novel family of transcriptional repressor proteins in the Bacteroidetes has been identified, orchestrating the canonical response to DNA damage in this phylum. The discovery sheds light on the origin and plasticity of the transcriptional network involved in the SOS response.

Summary: A new photolyase, SePhrB, has been characterized in Synechococcus elongatus, demonstrating its ability to repair 6-4 photoproducts in DNA. SePhrB contains an antenna chromophore called 8-HDF and can be photoreduced without external electron donors. These findings suggest a greater diversity of FeS-BCPs than previously thought and warrant further investigation.

Summary: This study theoretically investigated the orientation factor of fluorescence resonance energy transfer (FRET) between LH2 and A647. Molecular dynamics simulations and electronic coupling calculations were performed, and the results showed that A647 was approximately 26 angstrom away from the BChl assembly in LH2. The average orientation factor was predicted to be 1.55, significantly different from the isotropic mean value.

Summary: GATOR2 plays a crucial role in the formation of myelin sheath in brain development, by regulating the signaling of amino acids and growth factors to mTORC1. Disruption of GATOR2 impairs the proliferation and differentiation of oligodendrocyte precursor cells, leading to defective myelination in the brain.

Summary: Tyrosine sulfation is a post-translational modification that enhances protein-protein interaction specificity. Sulfotyrosyl residues (sTyrs) play important roles in various biological processes, including high-affinity interactions, viral entry, thrombin interaction, and collagen binding. The lack of discernible binding site consensus makes sTyr an interesting research topic. Improved methods and advanced techniques will contribute to the discovery and understanding of sTyr occurrence and function.

Summary: This study fills important gaps in the geographic scope of poultry farming using Life Cycle Assessment analysis. The results show that greenhouse gas emissions during the feed production phase are the main environmental impact. The study also proposes three scenarios, demonstrating that using poultry viscera meal can lead to better environmental outcomes.

Summary: Quinone redox reactions involve the stabilization of a semiquinone intermediate state through hydrogen bonding interactions. This study used electron paramagnetic resonance and quantum mechanical calculations to investigate the role of specific amino acids in stabilizing the semiquinone state. The results demonstrate that a mutation in the enzyme can significantly enhance the stability of the semiquinone and that certain spectroscopic features can serve as potential markers for specific amino acid interactions with the semiquinone.
