Characterization of the putative yeast mitochondrial triacylglycerol lipase Tgl2.
J Biol Chem
January 2025
Interfaculty Institute of Biochemistry, University of Tübingen, Tübingen, Germany. Electronic address:
Mitochondria derive the majority of their lipids from other organelles through contact sites. These lipids, primarily phosphoglycerolipids, are the main components of mitochondrial membranes. In the cell, neutral lipids like triacylglycerides (TAGs) are stored in lipid droplets, playing an important role in maintaining cellular health.

Department of Physics of Complex Systems, S. N. Bose National Centre for Basic Sciences, Block-JD, Sector-III, Salt Lake, Kolkata 700106, India.
In DNA double helices, Hoogsteen (HG) base pairing is an alternative mode of Watson-Crick (WC) base pairing. HG bp has a different hydrogen bonding pattern than WC bp. We investigate here the binding energy of homeodomain proteins with a HG-DNA duplex, where DNA adopts a HG bp in its sequence.

Biochemistry
January 2025
Laboratory of Clinical Biochemistry and Metabolism, Department of General Pediatrics, Adolescent Medicine and Neonatology, Faculty of Medicine, Medical Center, University of Freiburg, Freiburg im Breisgau 79106, Germany.
Human CblC catalyzes the indispensable processing of dietary vitamin B by the removal of its β-axial ligand and an either one- or two-electron reduction of its cobalt center to yield cob(II)alamin and cob(I)alamin, respectively. Human CblC possesses five cysteine residues of an unknown function. We hypothesized that Cys149, conserved in mammals, tunes the CblC reactivity.

January 2025
Academy of Interdisciplinary Studies on Intelligent Molecules, College of Chemistry, Tianjin Normal University, Tianjin 300387, China.
Peptide-based therapy is appealing in modern medicine owing to its high activity and excellent biocompatibility. Poor stability, leading to unacceptable bioavailability, severely constrains its clinical application. Here, we proposed a general supramolecular approach for improving the plasma resistance of a commercially available peptide agent, thymopentin.

Molecules
January 2025
Department of Inorganic and Analytical Chemistry, Poznan University of Medical Sciences, 60-780 Poznan, Poland.
The bioaccumulation of pesticides in honeybee products (HBPs) should be studied for a number of reasons. The presence of pesticides in HBPs can provide new data on the risk related to the use of pesticides and their role in bee colony losses. Moreover, the degree of contamination of HBPs can lower their quality, weaken their beneficial properties, and, in consequence, may endanger human health.
