The cysteine/arginine (Cys/Arg) branch of the N-degron pathway controls the stability of certain proteins with methionine (Met)-Cys N-termini, initiated by Met cleavage and Cys oxidation. In seeding plants, target proteins include the Group VII Ethylene Response Factors, which initiate adaptive responses to low oxygen (hypoxic) stress, as well as Vernalization 2 (VRN2) and Little Zipper 2 (ZPR2), which are involved in responses to endogenous developmental hypoxia. It is essential that these target proteins are only degraded by the N-degron pathway under the appropriate physiological conditions.

The microbial aminotransferase enzyme DapC is vital for lysine biosynthesis in various Gram-positive bacteria, including . Characterization of the enzyme's conformational dynamics and identifying the key residues for ligand binding are crucial for the development of effective antimicrobials. This study employs atomistic simulations to explore and categorize the dynamics of DapC in comparison to other classes of aminotransferase.

Ten-eleven translocation (TET) enzymes oxidize 5-methylcytosine (mC) in DNA, contributing to the regulation of gene transcription. Diverse mutations of TET2 are frequently found in various blood cancers, yet the full scope of their functional consequences has been unexplored. Here, we report that a subset of TET2 mutations identified in leukemia patients alter the substrate specificity of TET2 from acting on mC to thymine.

Hispidin (1) is a polyphenolic compound with a wide range of pharmacological activities that is distributed in both plants and fungi. In addition to natural extraction, hispidin can be obtained by chemical or enzymatic synthesis. In this study, the identification and characterization of an undescribed enzyme, PheG, from Phellinus igniarius (P.

Unlabelled: Human norovirus (HuNoV) is a leading cause of gastroenteritis worldwide and is associated with significant morbidity, mortality, and economic impact. There are currently no licensed antiviral drugs for the treatment of HuNoV-associated gastroenteritis. The HuNoV protease plays a critical role in the initiation of virus replication by cleaving the polyprotein.
