Functional heterogeneity of ubiquitin carrier proteins.
In the formation of covalent ubiquitin-protein conjugates that occurs during ATP- and ubiquitin-dependent proteolysis in reticulocyte extracts, ubiquitin (Ub) is activated to a thiol ester of the activating enzyme E1 (via the Ub carboxyl terminus), transferred to low-molecular weight "carrier proteins" (E2s) to form E2-Ub thiol esters, and then ...

Most MmpLs transport lipids and glycolipids of the complex mycomembrane of mycobacteria. This study shows that MmpL10 from Mycobacterium smegmatis, the transporter of the trehalose polyphosphate precursor, harbors a coiled‐coil‐like extension. Biochemical and electron microscopy studies demonstrate that the coiled‐coil enables MmpL10 to trimerize.

The mitochondrial receptor complex [PDF]
The receptor complex in the mitochondrial outer membrane, which consists of at least seven different proteins, is responsible for the recognition and translocation of cytosolically synthesized preproteins.

Evolutionary interplay between viruses and R‐loops
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

The number of circulating tumor cells obtained from prostate cancer patients was increased approximately 5‐fold compared to regular CellSearch when processing 2 mL diagnostic leukapheresis material aliquots and increased by 44‐fold when processing 20 mL DLA aliquots using the flow enrichment target capture Halbach‐array.

Glassy protein dynamics and gigantic solvent reorganization energy of plastocyanin [PDF]
We report the results of Molecular Dynamics simulations of electron transfer activation parameters of plastocyanin metalloprotein involved as electron carrier in natural photosynthesis. We have discovered that slow, non-ergodic conformational fluctuations of the protein, coupled to hydrating water, result in a very broad distribution of donor-acceptor ...

Distinct steps in the import of ADP/ATP carrier into mitochondria [PDF]
Transport of the precursor to the ADP/ATP carrier from the cytosol into the mitochondrial inner membrane was resolved into several consecutive steps. The precursor protein was trapped at distinct stages of the import pathway and subsequently chased to ...

Contact hypersensitivity to picrylchloride was induced in guinea pigs by the subcutaneous injection of heteroantigenic components which were isolated by antibody immunoadsorbent from soluble epidermal proteins of picrylchloride painted guinea pigs.

Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...
