Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

高铁酸钾与UV-vis/TiO₂协同氧化效应的研究

Gongye shui chuli, 2007
为研究高铁酸钾与紫外-可见光/二氧化钛(UV-vis/TiO2)光催化的协同氧化效应，以氨氮为目标物，研究了高铁酸钾、UV-vis/TiO2光催化以及高铁酸钾与UV-vis/TiO2光催化联用对水中氨氮的去除效果。结果表明，在高铁酸钾与UV-vis/TiO2光催化联用的条件下，在pH=8.0，温度为室温，反应时间为30min，氨氮质量浓度50mg/L，高铁酸钾、TiO2投加质量浓度分别为20、200mg/L时，水中氨氮的去除率为97.5%，比单独的高铁酸钾或UV-vis/TiO2最大去除率分别提高了22.

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Color and Near‐Infrared Reflectance Covary in Distinct Ways Across Taxa

Ecology and Evolution
Solar radiation reaching Earth spans 300–2500 nm, covering ultraviolet (UV), visible (Vis), and near‐infrared (NIR) wavelengths. Its reflectance is critical for animal signaling, camouflage, and thermoregulation, likely leading to selective trade‐offs ...
