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 ...

Roles of interbasin frequency changes in the poleward shifts of the maximum intensity location of tropical cyclones

Environmental Research Letters, 2015
An observed poleward migration in the average latitude at which tropical cyclones (TCs) achieved their lifetime-maximum intensities (LMIs) was previously explained by changes in the mean meridional environments favorable to storm development linked to ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Structural changes of world industry in post-industrial society and structural shifts in the world high-tech production allocation

Prace Komisji Geografii Przemysłu Polskiego Towarzystwa Geograficznego, 2010
This research is dedicated to the characteristic of structural spatial shifts of the world manufacturing industry. These trends have conduced to the restructuring of the world economy and main shifts in the manufacturing locations both at regional and ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

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 ...

Resilience and regime shifts: Assessing cascading effects [PDF]

, 2006
Most accounts of thresholds between alternate regimes involve a single, dominant shift defined by one, often slowly changing variable in an ecosystem.

Optimizing risk in action: Differences between fixated aim points and movement outcomes in throwing

Current Issues in Sport Science
Introduction Movement outcomes are inherently subject to variance. Handling this variance is crucial for successful sensorimotor behaviour – whether in everyday life or in sports –, particularly in high-risk situations.

REFINED METHOD OF DETERMINING THE LOCATION OF THE SOURCERADIATION ON A CURVE WAVE FRONT

Information and Telecommunication Sciences, 2016
Background. Despite the limited range, the device determines the location of the radio source along the curved front of the electromagnetic wave, allows using the diversity antenna system to solve the problem of the simultaneous determination of range ...

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.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...
