Integrated Analysis of Cross-Links and Dead-End Peptides for Enhanced Interpretation of Quantitative XL-MS.

Keller Andrew A Tang Xiaoting X Bruce James E JE

Journal of proteome research 20230808 9

Chemical cross-linking with mass spectrometry provides low-resolution structural information on proteins in cells and tissues. Combined with quantitation, it can identify changes in the interactome between samples, for example, control and drug-treated cells or young and old mice. A difference can originate from protein conformational changes that alter the solvent-accessible distance separating the cross-linked residues. Alternatively, a difference can result from conformational changes localiz ...[more]

Histone acetyltransferase 2 links H4 acetylation, H2A.Z deposition and transcription start site-choice in African trypanosomes

Project description:Both, acetylation of histones and of histone variant H2A.Z are conserved features of eukaryotic transcription start sites (TSSs) and both features appear to be critical for correct transcription initiation. However, complex patterns of transcriptional regulation have complicated the establishment of functional links between histone acetylation, H2A.Z deposition and their importance in transcription regulation. To elucidate these links, we took advantage of the unusual genome organization in Trypanosoma brucei, a highly divergent eukaryote. In T. brucei genes are organized in long polycistronic transcription units, drastically reducing the sites of transcription initiation. Employing a highly sensitive and quantitative mass-spectrometry-based approach, we quantified the genome-wide histone acetylation and methylation pattern and identified various acetyl and methyl marks exclusively enriched at TSSs In addition, we show that deletion of histone acetyltransferase 2 results in a loss of H4 acetylation at TSSs, a loss of H2A.Z deposition at TSSs and a shift in the sites of transcription initiation. Combined, our findings demonstrate an evolutionary conserved link between histone H4 acetylation, H2A.Z deposition and RNA transcription initiation.

Mitochondrial interactome quantitation reveals structural changes in metabolic machinery in failing murine heart

Project description:Advancements of cross-linking mass spectrometry (XL-MS) for structural analysis of proteins bridges the gap between purified systems and native tissue environments. Here, we utilize isobaric quantitative protein interaction reporter technology (iqPIR) to further extend XL-MS to the first system-wide comparative study of mitochondrial proteins from healthy and diseased murine hearts. The failing heart interactome includes 544 statistically significant cross-linked peptide pairs altered in disease condition. Structural insight into ketone oxidation metabolons, OXPHOS machinery, and nucleotide transporter hybrid-conformations, support mitochondrial remodeling in failing heart while bringing forth new hypotheses for pathological mechanisms. Application of quantitative cross-linking technology in live tissue provides molecular-level insight to complex biological systems difficult to model in cell culture, thus providing a valuable resource for study of human diseases.

Mapping the Interaction between Eukaryotic Initiation Factor 4A (eIF4A) and the Inhibitor Hippuristanol Using Carbene Footprinting and Mass Spectrometry

Project description:Protein-ligand interactions are central to protein activity and cell functionality. Improved knowledge of these relationships greatly benefits our understanding of key biological processes and aids in rational drug design towards the treatment of clinically relevant diseases. Carbene footprinting is a recently developed mass spectrometry-based chemical labelling technique that provides valuable information relating to protein-ligand interactions, such as the mapping of binding sites and associated conformational change. Here we show the application of carbene footprinting to the interaction between eIF4A helicase and a natural product inhibitor, hippuristanol, found in the coral Isis hippuris. Upon addition of hippuristanol we identified reduced carbene labelling (masking) in regions of eIF4A previously implicated in ligand binding. Additionally, we detected hippuristanol-associated increased carbene labelling (unmasking) around the flexible hinge region of eIF4A, indicating ligand-induced conformational change. This work represents further development of the carbene footprinting technique and demonstrates its potential in characterising medicinally relevant protein-ligand interactions.

DEAD-box ATPase Dbp2 mediates mRNA release after 3’-end formation

Project description:mRNA biogenesis in the eukaryotic nucleus is a highly complex process. The numerous RNA processing steps are spatially and temporally coordinated to ensure that only fully processed transcripts are released into the nucleoplasm for export from the nucleus. Here, we explore the hypothesis that fission yeast Dbp2, a ribonucleoprotein complex (RNP) remodelling ATPase of the DEAD-box family, is involved in a RNP assembly checkpoint at the 3’-end of genes that is coupled to the release of the 3’-end processing complex after polyadenylation. We show that Dbp2 interacts with the cleavage and polyadenylation complex (CPAC) and localizes to cleavage bodies, which are enriched for 3’-end processing factors and proteins involved in nuclear RNA surveillance. Upon loss of Dbp2, 3’-processed, polyadenylated RNAs accumulate on chromatin and in cleavage bodies, which is accompanied by a depletion of CPAC components from the soluble pool. Under these conditions, cells display an increased likelihood to skip polyadenylation sites as well as delayed transcription termination, suggesting that the availability of CPAC components is insufficient to maintain normal levels of 3’-end processing. Our data is consistent with a model in which Dbp2 is involved in an mRNP remodelling checkpoint that licenses RNA export and is coupled to CPAC release.

Two distinct ferredoxins are essential for nitrogen fixation by the iron nitrogenase in Rhodobacter capsulatus

Project description:Nitrogenases are the only enzymes able to ‘fix’ gaseous nitrogen into bioavailable ammonia and, hence, are essential for sustaining life. Catalysis by nitrogenases requires both a large amount of ATP and electrons donated by strongly reducing ferredoxins or flavodoxins. Our knowledge about the mechanisms of electron transfer to nitrogenase enzymes is limited, with electron transport to the iron (Fe)-nitrogenase having hardly been investigated. Here, we characterised the electron transfer pathway to the Fe-nitrogenase in Rhodobacter capsulatus via proteome analyses, genetic deletions, complementation studies and phylogenetics. Proteome analyses revealed an upregulation of four ferredoxins under nitrogen-fixing conditions reliant on the Fe-nitrogenase in a molybdenum nitrogenase knockout strain (nifD), compared to non-nitrogen-fixing conditions. Based on these findings, R. capsulatus strains with deletions of ferredoxin (fdx) and flavodoxin (fld, nifF) genes were constructed to investigate their roles in nitrogen fixation by the Fe-nitrogenase. R. capsulatus deletion strains were characterised by monitoring diazotrophic growth and nitrogenase activity in vivo. Only deletion of fdxC or fdxN resulted in slower growth and reduced Fe-nitrogenase activity, whereas the double-deletion of both fdxC and fdxN abolished diazotrophic growth. Differences in the proteomes of ∆fdxC and ∆fdxN strains, in conjunction with differing plasmid complementation behaviours of fdxC and fdxN, indicate that the two Fds likely possess different roles and functions. These findings will guide future engineering of the electron transport systems to nitrogenase enzymes, with the aim of increased electron flux and product formation.

Emergence of enhanced metabolic entanglement during experimental evolution of an interkingdom microbial community

Project description:Obligate symbioses have likely evolved through multiple intermediate steps, resulting in a gradual erosion of independence of initially autonomous entities. Here we observed progression towards an increased entanglement for an engineered mutualistic consortium between Escherichia coli and Saccharomyces cerevisiae. Experimental evolution of this interkingdom community led to a rapid enhancement of metabolic cooperation between partners, including the reinforcement of both selfish and social traits, along with the emergence of a novel dependence of yeast on the bacterial partner for ammonium assimilation. Selection on social traits repeatedly occurred indirectly, via pleiotropies and trade-offs within the cellular regulatory networks, and without the requirement for group selection. We propose that such indirect selection on traits may be a common mechanism in evolutionary transitions towards sociality.

The virulence regulator VirB from Shigella flexneri uses a CTPdependent switch mechanism to activate gene expression

Project description:The transcriptional antisilencer VirB acts as a master regulator of virulence gene expression in the human pathogen Shigella flexneri. It binds defined sequences (virS) upstream of VirB-dependent promoters and counteracts their silencing by the nucleoid-organizing protein H-NS. However, its precise mode of action remains unclear. Notably, VirB is not a classical transcription factor but related to DNA partitioning pro- teins of the ParB family, which have recently been recognized as DNA-sliding clamps using CTP binding and hydrolysis to control their DNA entry gate. Here, we show that VirB binds CTP, embraces DNA in a clamp-like fashion upon its CTP-dependent loading at virS sites and slides laterally on DNA after clamp closure. Mutations that prevent CTP binding block the loading of VirB clamps in vitro and the formation of VirB nucleoprotein complexes in vivo. Thus, VirB represents a CTP-dependent molecular switch that uses a loading-and-sliding mechanism to control transcription during bacterial pathogenesis.
