Redox signals and oxidative stress in the control of mitochondrial protein import

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract Mitochondrial protein import is essential for organelle biogenesis and cellular homeostasis. It operates in an environment that is intrinsically shaped by redox chemistry. Mitochondria are major sources of reactive oxygen species (ROS), which arise as by‐products of oxidative phosphorylation. Cells therefore maintain sophisticated ROS‐handling

The pivotal role of β‐lactone stereochemistry in the development of SARS‐CoV‐2 Mpro inhibitors

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract From the arrival of the SARS‐CoV‐2 coronavirus in 2019 and its associated COVID‐19 pandemic, worldwide efforts have been focused on developing a drug to treat patients. The SARS‐CoV‐2 main protease (Mpro) is one of the main targets for drug design due to its key role in the virus replication and its distinguished ability to cleave peptides ...

Small molecules as arthropod kinin receptor antagonists, feeding modulators, or novel mosquitocidal agents

open access: yesPest Management Science, Volume 82, Issue 7, Page 6842-6863, July 2026.
A two‐pronged screen of small molecules – (1) on recombinant kinin receptor and (2) through topical application – identifies kinin receptor antagonists, feeding behavior modulators, and new mosquitocidal molecules. Abstract BACKGROUND Aedes aegypti and Culex quinquefasciatus mosquitoes are primary vectors for numerous human and animal pathogens and ...

Histidine Ethylation by Histidine Methyltransferases SETD3 and METTL9

open access: yesChemBioChem, Volume 27, Issue 12, 26 June 2026.
Enzyme assays and computational analyses reveal that human histidine methyltransferases SETD3 and METTL9 have a capacity to catalyze histidine ethylation in the presence of synthetic or in situ produced S‐adenosylethionine (AdoEth) and Se‐adenosylselenoethionine (AdoSeEth) cosubstrates.

Mutagenic Survey of Key Residues of NifB Involved in Radical SAM‐Dependent Nitrogenase Cofactor Assembly

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
NifB uses an RS–K1–K2 triad to assemble the L‐cluster, a [Fe8S9C] precursor of the nitrogenase cofactor. The RS module cleaves SAM to form the 5′‐dA radical, K1 serves structural/SAM‐sensing roles, and K2 drives radical‐dependent fusion with K1. SAM‐anchoring residues link SAM binding to cluster fusion, while termini and surface residues regulate ...
