An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Direct Phase Angle and Voltage Amplitude Model Predictive Control of a Power Converter for Microgrid Applications

open access: yesEnergies, 2018
Several control strategies of the finite control set model predictive controls (FCS-MPC) have been proposed for power converters, such as predictive current control (PCC), direct predictive power control (DPPC), and predictive voltage control (PVC ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Design of Super-Twisting Algorithm Based Sliding Mode Control for 9-Level Packed E-Cell Inverters

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2021
In this paper, a super twisting algorithm based sliding mode control method is presented for 9-Level Packed E-Cell inverters. Regulating the load voltage is the main objective in the control of off-grid inverters.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Quantitative stability analysis of STATCOM in voltage control mode and Enhanced control method based on voltage feedforward

open access: yesInternational Journal of Electrical Power & Energy Systems
STATCOM is a crucial device for reactive power compensation and voltage regulation. However, under weak grid conditions, oscillations may arise during voltage control (VC) mode operation due to the AC Voltage Controller (AVC), potentially jeopardizing ...
