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 ...

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.

Axial mixing with spiral-shaped channel micromixer
Journal of Fluid Science and Technology, 2015 Axial fluctuations in carrier concentrations cause detection noise during chemical analysis using flowing carrier streams. Here, we report a method of axial mixing using serially cascaded microchannel units with branches and junctions.

Axial Dispersion in Gas-Bubble Columns
Chemical engineering, 1971 本研究では前報の流動モデルの理論を拡張し, 循環速度分布の存在は平均流方向での混合となることに基づいて, Taylor, Ticha・cekらによって論じられた速度分布モデルを適用し, 気泡塔装置の乱流域における軸方向混合拡散についての理論式を導いた。この結果に対し, 前報で得られた実験式を導入して, 気泡塔への適用を試みた。総括の混合拡散係数を, 平均循環速度と塔径基準のPe数で表現し, また, 混合拡散に対するガス空塔速度と塔径の影響を示す相関式を導いた。

RNA‐related functions of BRCA2 in transcription, replication, and genome stability
FEBS Letters, EarlyView.Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

FEBS Letters, EarlyView.Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein
FEBS Letters, EarlyView.Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.
