Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Continuous Control Set Model Predictive Control for an Indirect Matrix Converter

Energies, 2021
A continuous control set model predictive power control strategy for an indirect matrix converter is proposed in this paper. The load reactive power, the load active power, and the input reactive power are controlled simultaneously. This control strategy

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

FEBS 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.

Under the IOT Platform a Novel Algorithm for Minimization of Current Pulsation in PFC Circuit

IEEE Access, 2018
In order to achieve the IOT, in the traditional one-cycle controlled PFC circuit, the system's switching losses considerably increase with the control switching frequency and the system's power, severely affecting the system's efficiency.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

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+.

Sub-volt switching of nanoscale voltage-controlled perpendicular magnetic tunnel junctions

Communications Materials, 2022
Voltage-controlled magnetic random-access memory is promising for high-performance computing applications. Here, a perpendicular magnetic tunnel junction structure with high voltage-controlled magnetic anisotropy coefficient is developed, allowing sub ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Performance oriented control over networks: Switching controllers and switched time delay [PDF]

Asian Journal of Control, 2006
AbstractThe stability and performance of a networked control system (NCS) strongly depends on the communication quality, e.g., the communication time delay. Aiming for performance oriented control over networks in the presence of piecewise constant time delay, two novel control approaches are investigated.
