The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Static and dynamic behaviours of helical spring in MR fluid [PDF]

open access: yes, 2016
MR fluid has been used in automobile industry for vibration suppression device. However its dynamic interaction between structural spring and electro-magnetised MR fluid has not been thoroughly investigated.

Elastic Deformation Effects on Self-Lubricating Journal Bearings Using Pseudo-Plastic Lubricants

open access: yesTribology Online, 2021
In this study, we have analyzed the effect of elastic deformations on the static characteristics of finite self-lubricating journal bearings. This analysis takes into account the rheological lubricant behavior which obeys to Rabinowitsch law.

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

open access: yesFEBS 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.

The measurement of near wall flows using pneumatic wedge probes. [PDF]

open access: yes, 1995
The three hole, wedge-type pneumatic pressure probe represents a robust traverse probe design which is widely used for total and static pressure and yaw angle measurements in turbomachinery.

Cylindrical symmetric, non-rotating and non-static or static black hole solutions and the naked singularities

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
In this work, a four-dimensional cylindrical symmetric and non-static or static space-times in the backgrounds of anti-de Sitter (AdS) spaces with perfect stiff fluid, anisotropic fluid and electromagnetic field as the stress–energy tensor, is presented.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

EXPERIMENTAL STUDY OF MAGNETIC FLUID SEAL

open access: yesНаука и техника, 2006
Dependences of critical pressure drop, being held by magnetic fluid seal, on time in a static state and shaft rotation velocity in dynamics have been experimentally determined.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
