Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS 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 ...

A study on “position-energy” response correction method based on monolithic crystal coupled SiPM array

open access: yesNukleonika
The intrinsic characteristics of the monolithic crystal detector are spatially inconsistent, which leads to the position dependence of the detector on the energy response of the γ-ray as well as the peak shift of the response spectrum of the detector ...

Investigating the onset of energy dissipative processes in heavy ion fusion using MANTEIS [PDF]

open access: yesEPJ Web of Conferences
On the path to fusion, nuclei dissipate their initial kinetic energy into internal excitation, but the understanding of how energy dissipation during the collision affects the resulting fusion cross-sections is still limited.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS 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.

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

open access: yesFEBS 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 ...

Quantum detector tomography of a time-multiplexed superconducting nanowire single-photon detector at telecom wavelengths [PDF]

open access: yes, 2013
Superconducting nanowire single-photon detectors (SNSPDs) are widely used in telecom wavelength optical quantum information science applications. Quantum detector tomography allows the positive-operator-valued measure (POVM) of a single-photon detector ...

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life

open access: yesFEBS Letters, EarlyView.
Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

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

open access: yesFEBS 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 ...

High Energy Neutron Detector [PDF]

open access: yesReview of Scientific Instruments, 1948
A neutron detector which utilizes the fission of bismuth and responds only to neutrons of energy greater than about 50 Mev is described. The efficiency is low (about 10−6), but the instrument is suitable for monitoring a high energy neutron beam and for beam attenuation measurements.
