Viral fusion proteins: multiple regions contribute to membrane fusion
In recent years, the simple picture of a viral fusion protein interacting with the cell and/or viral membranes by means of only two localized segments (i.e. the fusion peptide and the transmembrane domain) has given way to a more complex picture in which multiple regions from the viral proteins interact with membranes.

Calpain small subunit homodimerization is robust and calcium‐independent
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Characterization of structural and immunological properties of a fusion protein between flagellin from Salmonella and lumazine synthase from Brucella [PDF]
Aiming to combine the flexibility of Brucella lumazine synthase (BLS) to adapt different protein domains in a decameric structure and the capacity of BLS and flagellin to enhance the immunogenicity of peptides that are linked to their structure, we ...

This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Class II Fusion Proteins [PDF]
Enveloped viruses rely on fusion proteins in their envelope to fuse the viral membrane to the host-cell membrane. This key step in viral entry delivers the viral genome into the cytoplasm for replication. Although class II fusion proteins are genetically and structurally unrelated to class I fusion proteins, they use the same physical principles and ...

Development of a novel fusion system for soluble protein overexpression and purification in Escherichia coli [PDF]
Recombinant protein production is a useful technology for therapeutic and diagnostic applications. The bacterium Escherichia coli is widely used for the bioproduction of proteins, but still presents some drawbacks.

Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Introducere. Pacienţii cu leucemie acuta limfoblastică (LAL) neonatală prezintă în mod frecvent, o tran- slocaţie particulară, t(4;ll)(q21;q23), care duce la fuziunea genei MLL (mixed lineage leukemia) de pe cromo- zomul 11 cu gena AF4 de pe cromozomul 4.

Broad activation of the ubiquitin-proteasome system by Parkin is critical for mitophagy [PDF]
Parkin, an E3 ubiquitin ligase implicated in Parkinson's disease, promotes degradation of dysfunctional mitochondria by autophagy. Using proteomic and cellular approaches, we show that upon translocation to mitochondria, Parkin activates the ubiquitin ...
