Temperature Regulates Stability, Ligand Binding (Mg2+ and ATP) and Stoichiometry of GroEL/GroES Complexes

, 2021
Chaperonins are nanomachines that harness ATP hydrolysis to power and catalyze protein folding, chemical action that is directly linked to the maintenance of cell function through protein folding/refolding and assembly.

Temperature Fluctuation Attenuation of Circulating Cooling Water Using Dynamic Thermal Filtering

Applied Sciences, 2020
The Demand for circulating cooling water (CCW) with high temperature stability and a quick response to temperature control is essential for precision engineering, so a dynamic thermal filtering method is proposed in this paper.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Hydroxypropyl Cellulose Polymers as Efficient Emulsion Stabilizers: The Effect of Molecular Weight and Overlap Concentration

Gels
Hydroxypropyl cellulose (HPC) is a non-digestible water-soluble polysaccharide used in various food, cosmetic, and pharmaceutical applications. In the current study, the aqueous solutions of six HPC grades, with molecular mass ranging from 40 to 870 kDa,

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Automated in-situ calibrations at the Curie temperature of ferroelectric materials [PDF]

At industrial process conditions, the reading of thermometers can change or drift over time. To reduce the risk of having such undetected errors in the measurement, thermometers can be recalibrated periodically off-process, which is an elaborate and ...

A Plasmonic Fiber Based Glucometer and Its Temperature Dependence

Micromachines, 2018
We present the plasmonic fiber based optical glucometer. A thin gold layer is coated on clad-free core of multimode optical fiber along 3 cm length to excite surface plasmons at 632.8 nm wavelength. Glucose oxidase is immobilized on the metal surface for

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.
