Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Stability to perturbations of continued fraction approximants and applications

Researches in Mathematics
The paper investigates the problem of stability to perturbations of continued fraction approximants with complex elements. Unlike the problem of investigating the stability of continued fractions to perturbations, which focuses on the properties of ...

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

FEBS 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 ...

INFLUENCIA DE LA TOPOLOGIA EN EL CONDICIONAMIENTO DE MATRICES DE REDES ELÉCTRICAS TOPOLOGIC INFLUENCE ON THE CONDITIONING OF MATRICES OF ELECTRIC NETWORKS

Ingeniare: Revista Chilena de Ingeniería, 2008
Se estudia la influencia de la topología de redes eléctricas y alimentadores en el condicionamiento de las matrices asociadas a su modelado matemático. Se observa que el número de condición de estas matrices tiene una gran dependencia de la estructura de

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

FEBS 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

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

FEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics
