An Efficient CO2‐Upcycling Platform Based on Engineered Halomonas TD with Enhanced Acetate‐Utilizing Capacity via Adaptive Laboratory Evolution

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
An electrochemical system is designed to convert CO2 into CO2‐derived electrolytes (CDE), mainly containing acetate and formate. The underlying mechanism of acetate metabolism in Halomonas TD80 is explored via ALE. Engineered TD80 produced high‐yield diversified products from CDE.

Unveiling the fructose metabolism system in Staphylococcus aureus: insights into the regulatory role of FruR and the FruRKT operon in bacterial fitness

open access: yesBMC Microbiology
Background The utilization of fructose as a carbon source and energy provider plays a crucial role in bacterial metabolism. Additionally, fructose metabolism directly impacts the pathogenicity and virulence of certain pathogenic microorganisms.

Failed "nonaccelerating" models of prokaryote gene regulatory networks

open access: yes, 2004
Much current network analysis is predicated on the assumption that important biological networks will either possess scale free or exponential statistics which are independent of network size allowing unconstrained network growth over time. In this paper,

The Importance of Being Imperfect: Structure and Function of Bacterial Amyloid

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
Functional bacterial amyloids such as CsgA and FapC have been widely studied to understand the relationship between aggregation and function. The recently solved structure of FapC reveals a Greek‐key motif in which extensive hydrogen bonding and packing interactions formed by residues in conserved imperfect repeats stabilize a β‐solenoid core.

A Tolerogenic Plasmid Inhibits Autoantibody Production Triggered by Immunization With Human Peptidyl Arginine Deiminase 4

open access: yesArthritis &Rheumatology, Volume 78, Issue 1, Page 80-89, January 2026.
Objective Rheumatoid arthritis (RA) is usually preceded and likely mediated by autoantibodies to citrullinated proteins (ACPAs) that recognize citrulline residues on multiple proteins. Conversion of arginine into citrulline is performed by enzymes called peptidyl arginine deiminases (PADs). We have previously demonstrated that the human PAD4 (hPAD4) is
