Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Study of the TEC data obtained from the DORIS stations in relation to seismic activity
Annals of Geophysics, 2007 Ionospheric data obtained from the DORIS system are used in this paper. The DORIS system is composed of several ground-based beacons which emit at two frequencies (400 MHz and 2 GHz) and of receivers on board several satellites (currently SPOT2,

Development of Ionospheric Tomography Model Using GPS [PDF]
Journal of Astronomy and Space Sciences, 2006 We produced the electron density distribution in the ionosphere over South Korea using the data from nine permanent GPS (Global Positioning System) stations which have been operated by KASI (Korea Astronomy and Space Science Institute).

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Variability of the total radiation belt electron content [PDF]
Journal of Geophysical Research: Space Physics, 2009 To quantify radiation belt variability, while de‐emphasizing internal transport, the total number of electrons in the outer belt has been computed from data taken on the Polar satellite as a function of time throughout 1998 and of kinetic energy in the range 0.8 to 6.4 MeV.
