Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

An Improved Big Bang-Big Crunch Algorithm for Estimating Three-Phase Induction Motors Efficiency [PDF]

Journal of Operation and Automation in Power Engineering, 2016
Nowadays, the most generated electrical energy is consumed by three-phase induction motors. Thus, in order to carry out preventive measurements and maintenances and eventually employing high-efficiency motors, the efficiency evaluation of induction ...

Energy efficiency of induction motors in agriculture

, 2011
The paper points to some possibilities for increasing the energy efficiency of asynchronous electric motors with special emphasis on the use and energy efficiency in agricultural production. The most important measures in this regard should be taken are: the application of energy-efficient induction motors, selection of motors based on electric power ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Improving energy efficiency of motor vehicles

Technical sciences and technologies
Паливна економічність автомобілів із двигунами внутрішнього згоряння (ДВЗ) є одним із ключових показників їхніх експлуатаційних характеристик, оскільки витрати на паливо суттєво впливають на собівартість перевезень вантажів і пасажирів. Підвищення енергоефективності автотранспортних засобів (АТЗ) є важливим і актуальним завданням, яке дозволяє зменшити

The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

FEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.
