Perturbations in fumarate levels in Plasmodium berghei leads to cysteine succination and impairs ookinete formation

This study demonstrates that perturbing fumarate metabolism in *Plasmodium berghei* leads to cysteine succination and oxidative stress, which specifically impairs ookinete formation while sparing erythrocytic stages, thereby highlighting parasite-specific fumarate hydratase as a promising target for transmission-blocking antimalarial drugs.

Living Cells Employ Ubiquitin-Proteasomal System and Nucleotide Excision Repair Pathways to Remove Reactive Oxygen Species-Induced DNA-Protein Crosslinks (ROS-DPCs).

This study identifies over 100 proteins involved in forming toxic ROS-induced DNA-protein crosslinks (ROS-DPCs) in human cells and elucidates how the ubiquitin-proteasomal system, SPRTN metalloprotease, and nucleotide excision repair pathways collaborate to remove these lesions, while also demonstrating that a stable glutathione analog can prevent their formation as a potential therapeutic strategy.

Conformational dynamics of the membrane-anchored foldase LipH from Pseudomonas aeruginosa governs recognition and release of its client lipase

This study reveals that the membrane-anchored foldase LipH from *Pseudomonas aeruginosa* utilizes intrinsic conformational dynamics and membrane interactions to transiently occlude its chaperone cavity, thereby balancing the initial capture and folding of the LipA lipase via its MD2 domain with the subsequent release of the mature client to facilitate efficient secretion.

In Cellulo pharmacological profiling and genomic editing reveals paralog-specific targets for PA generation during PLC signaling

This study utilizes pharmacological profiling and genomic editing to demonstrate that while DGK inhibitors like R59022 and BMS-502 exhibit paralog-specific effects on DGKalpha, effective reduction of phosphatidic acid levels during PLC signaling requires the simultaneous inhibition of both DGKalpha and phospholipase D enzymes.

Self-Sufficient Maturation and Catalysis of a Clade E CODH Encoded in a CooCTJ-Operon from Clostridium pasteurianum BC1

This study reports the heterologous production and characterization of a self-sufficient Clade E carbon monoxide dehydrogenase (CpBC1CODH-III) from *Clostridium pasteurianum* BC1, demonstrating that while its co-expression with the CooCTJ maturation machinery stabilizes the enzyme, its catalytic activity is primarily limited by nickel availability rather than maturation efficiency.
