Project description:The antibacterial mechanism towards S. aureus related with influencing electron transfer chain
| PRJNA777398 | ENA
Project description:The electron transfer chain is organized into inner mitochondrial membrane supercomplexes that promote substrate channeling and catalytic efficiency. This study shows that fatty acid oxidation enzymes physically interact with electron transfer chain supercomplexes at two points. The fatty acid oxidation trifunctional protein interacts with the NADH-binding domain of complex I of the electron transfer chain, while electron transfer flavoprotein dehydrogenase interacts with electron transfer chain complex III. These findings provide first view of an integrated molecular architecture for the major energy generating pathways in mitochondria.

Project description:In addition to leaves, the main site of photosynthetic reactions, active photosynthesis also takes place in stems, siliques and tree trunks. Although non-foliar photosynthesis has a marked effect on plant growth and yield, only limited information on the expression patterns of photosynthesis-related genes and the structure of photosynthetic machinery in different plant organs has been available. Here, we report the results of transcriptomic analysis of various organs of Arabidopsis thaliana and compare the gene expression profiles of young and mature leaves with a special focus on photosynthetic genes. Further, we analyzed the composition and organization of the photosynthetic electron transfer machinery in leaves, stems and green siliques at the protein level using BN-PAGE. RNA-Seq analysis revealed unique gene expression profiles in different plant organs and showed major differences in the expression of photosynthesis-related genes in young as compared to mature rosettes. Gel-based proteomic analysis of the thylakoid protein complex organization further showed that all studied plant organs contain the necessary components of the photosynthetic electron transfer chain. Intriguingly, stems accumulate high amounts of PSI-NDH complex, which has previously been implicated in cyclic electron transfer.

Project description:Geobacter species are of great interest for environmental and biotechnology applications as they can carry out direct electron transfer to insoluble metals or other microorganisms and have the ability to assimilate inorganic carbon. Here, we report on the capability and key enabling metabolic machinery of Geobacter metallireducens GS-15 to carry out CO2 fixation and direct electron transfer to iron. An updated metabolic reconstruction was generated, growth screens on targeted conditions of interest were performed, and constraint-based analysis was utilized to characterize and evaluate critical pathways and reactions in G. metallireducens. The novel capability of G. metallireducens to grow autotrophically with formate and Fe(III) was predicted and subsequently validated in vivo. Additionally, the energetic cost of transferring electrons to an external electron acceptor was determined through analysis of growth experiments carried out using three different electron acceptors (Fe(III), nitrate, and fumarate) by systematically isolating and examining different parts of the electron transport chain. The updated reconstruction will serve as a knowledgebase for understanding and engineering Geobacter and similar species.

Project description:Ever since the identification of the first protein-arginine kinase, McsB, in B. subtilis arginine phosphorylation gained more attention. However, the analysis of phosphorylations especially phosphormaidates comes along with several challenges. The sub-stoichiometric nature of protein phosphorylation requires proper enrichment strategies prior to LC-MS/MS analysis and the acid instability of phosphoramidates was long though to impede those enrichments. Further good spectral quality is required which can be reduced by the presence of neutral losses of phosphoric acid upon higher energy collision induced dissociation. Adaptation of common enrichment strategies to less acidic conditions and the use of electron-transfer dissociation allowed the identification of more than 200 pArg sites in B. subtilis and S. aureus so far. Here we show that pArg is stable enough for commonly used Fe3+-IMAC enrichment followed by LC-MS/MS and that HCD is still the gold standard for phosphoproteomics. By profiling a serine/ threonine kinase (Stk1) and phosphatase (Stp1) mutant from a methicillin-resistant S. aureus mutant library, we identified 1062 pArg sites and thus the most comprehensive arginine phosphoproteome to date. Using synthetic phosphoarginine peptides we validated the presence and localization of arginine phosphorylation in S. aureus and lastly, we could show that Stp1 is influencing the arginine phosphoproteom without being a protein-arginine phosphatase.
