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 ...

COMMODITY PRICES AND UNIT ROOT TESTS

open access: yes
Endogenous variables in structural models of agricultural commodity markets are typically treated as stationary. Yet, tests for unit roots have rather frequently implied that commodity prices are not stationary. This seeming inconsistency is investigated

Root architecture and morphometric analysis of Arabidopsis thaliana grown in metal-gradient agar dishes

open access: yes, 2014
This study aims at elucidating root reactions to the toxic heavy metals cadmium, copper and zinc at sub-toxic concentrations (10 μM CdSO4, 5 μM CuSO4, and 150 μM ZnSO4). For this purpose, we devised a new screening strategy using Petri dishes (12 x 12 cm)

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 ...
