Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Simulation Study for the Adsorption of Carbon Disulfide on Hydroxyl Modified Activated Carbon

open access: yesMolecules, 2023
In this study, grand canonical Monte Carlo simulations (GCMC) and molecular dynamics simulations (MD) were used to construct models of activated carbon with hydroxyl-modified hexachlorobenzene basic unit contents of 0%, 12.5%, 25%, 35% and 50%.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

One-step thermochemical activation of waste wood for micropollutant adsorption: Optimisation via design of experiments

open access: yesCase Studies in Chemical and Environmental Engineering
The increasing generation of waste wood (WW) and the demand for activated carbon (AC) in wastewater treatment highlight the need for sustainable alternatives. WW was converted into AC via one-step thermochemical activation using carbon dioxide, steam, or

Synergistic Optimization of Double Layer Capacitance and Pseudocapacitance of Activated Carbon by Nickel Oxide Loading

open access: yesInternational Journal of Electrochemical Science, 2019
Low concentration basic nickel carbonate is selected to load nickel oxide on sargassum-based activated carbon to improve the gravimetric capacitance of activated carbon electrode materials. Based on the pyrolysis characteristics of basic nickel carbonate,

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Controlling sub-nanometer pore-entrance size enables kinetic separation of Li+, Na+, and K+ in capacitive deionization

open access: yesCarbon Trends
Efficient recovery of lithium and potassium from saline resources is vital for energy storage and global food security. We present a novel capacitive deionization (CDI) approach employing carbon molecular sieve (CMS) electrodes with precisely tuned sub ...

Smaller is better: nanobodies meet NMR

open access: yesFEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.
