FEBS 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 ...

Differential Dynamic Microscopy of Bacterial Motility
Physical Review Letters, 2011 4 pages, 4 figures. In this updated version we have added simulations to support our interpretation, and changed the model for the swimming speed probability distribution from log-normal to a Schulz distribution.

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

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

c-di-GMP-mediated pause behavior enables Pseudomonas aeruginosa navigation in porous environments
Applied and Environmental MicrobiologyBacteria frequently encounter porous environments in nature and clinical settings, yet how single-flagellated pathogens navigate such confined spaces remains unclear.

Ecological relevance of flagellar motility in soil bacterial communities
Flagellar motility is a key bacterial trait as it allows bacteria to navigate their immediate surroundings. Not all bacteria are capable of flagellar motility, and the distribution of this trait, its ecological associations, and the life history ...

FEBS Letters, EarlyView.Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Prolonged CBD Exposure Is Associated with Higher Expression of flgA in Salmonella Typhimurium
AntibioticsBackground/Objectives: Salmonella Typhimurium is a Gram-negative foodborne pathogen that remains a major public-health concern. In this study, we examined whether prolonged exposure to cannabidiol (CBD) was associated with altered flgA expression and ...

Antimicrobial surfaces based on self-assembled nanoreactors : from block copolymer synthesis to bacterial adhesion study [PDF]
, 2010 The aim of this work is to develop a new strategy for the prevention of biofilm growth. For this purpose, we prepared bioactive surfaces resulting from the surface-immobilization of nanoreactors self-assembled from amphiphilic poly(isobutylene)-block ...
