Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Comparison of simplified methods for the optimisation of water distribution systems

, 2012
Evolutionary algorithms have been applied for the last 20 years to find near-optimal designs of water distribution systems (WDS). However, they suffer the disadvantage that they require a significant amount of computer time, especially for water ...

Rehabilitation, repairing and leakage detection optimization in water distribution systems

, 2006
Pipe ageing leads to an increment both in breakage frequency and leakages, and to a decrement in the system efficiency. Strategies are then necessary to define when and where to operate in order to improve the water distribution system reliability and to

Cross‐Scale Decoupling Kinetic Processes in Lithium‐Ion Batteries Using the Multi‐Dimensional Distribution of Relaxation Time

Advanced Science
To non‐destructively resolve and diagnose the degradation mechanisms of lithium‐ion batteries (LIBs), it is necessary to cross‐scale decouple complex kinetic processes through the distribution of relaxation times (DRT). However, LIBs with low interfacial
