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 ...

Measurement of branching fractions of color-suppressed decays of the (B)over-bar(0) meson to D-(*)0 pi(0), D-(*)0 eta, D-(*)0 omega, and D-0 eta `

open access: yes, 2004
Using a sample of 88.8×10^6 BB̅ events collected with the BABAR detector at the PEP-II storage rings at the Stanford Linear Accelerator Center, we measure the branching fractions of seven color-suppressed B-meson decays: B(B0→D0π0)=[2.9±0.2(stat)±0.3 ...

Effectiveness of the Initial Escalation of Immunochemotherapy in Patients with High Risk MALT-Lymphoma: Pilot Study Results

open access: yesКлиническая онкогематология
Background. MALT-lymphoma is usually characterized with an indolent course. The factors underlying the effectiveness of the standard chemotherapy in patients with MALT-lymphomas include MALT-IPI risk group and a high SUVmax according to the results of ...

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

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

open access: yesFEBS 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

The Association Between Serum Vitamin D Concentration and Nueromuscular Function in Patients with Crohn's Disease [PDF]

open access: yes, 2007
Serum vitamin D concentrations are not typically assessed in patients with Crohn's disease, even though neuromuscular complaints are one of the most common complaints observed.
