Detailed molecular characterization of a constitutively active bacterial NADPH oxidase (NOX) provides clues to the activation mechanism required to trigger electron transfer and reactive oxygen species (ROS) production in tightly regulated eukaryotic NOX.
2-Oxoglutarate and Fe(II)-dependent dioxygenases from clade C23 are the major source of guanidine in plants and release guanidine from arginine or homoarginine by C5 or C6 hydroxylation, respectively.

In individuals with type 2 diabetes, downregulation of bone canonical Wnt signaling is linked to higher levels of advanced glycation end-products within the bone, contributing to lower bone strength.
The bacterial AAA+ chaperone ClpL recognizes aggregated proteins via multiple contacts of its unique N-terminal domain and refolds them with high efficiency providing superior heat resistance.
DePARylation is essential for cell survival and thus poly(ADP-ribose) glycohydrolase (PARG) expression correlates with cytotoxicity induced by PARG inhibition, which will benefit the development of PARG inhibitors for cancer treatment.
Multifaceted properties of the water-soluble derivative of antibiotic heliomycin enable it to offer greater antitumor value than its parent compound by inhibiting the tNOX-NAD+-SIRT1 axis to induce apoptosis.

Thioredoxin functions as a negative allosteric effector of ASK1 by altering the interaction between the thioredoxin-binding and tetratricopeptide repeats domains, thereby reducing access to the kinase domain's activation segment.
New ATP-competitive inhibitors show properties of conformation selection when complexed with the MAP kinase, ERK2, altering movements around the activation loop.
