Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

General Design Layout of Datengxia Ship Lock
The Datengxia hydro project is a key project to open the 100-million-ton golden waterway of the Xijiang River,with high navigation requirements for the dam-site reach and a huge freight volume.The general design layout of the navigation structure ship ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

A comparison between internal protein nanoenvironments of α-helices and β-sheets.
Secondary structure elements are generally found in almost all protein structures revealed so far. In general, there are more β-sheets than α helices found inside the protein structures.

Quantitative predictions are presented of a depletion-induced torque and force acting on a single colloidal hard rod immersed in a solvent of hard spheres close to a planar hard wall. This torque and force, which are entirely of entropic origin, may play

Key-lock pair mechanism for access control using tribes of Farey fractions. [PDF]
We propose a new single key-lock mechanism based on the concept of an access control matrix. In this system, each file is given a lock and each user is given a key and through simple operations on keys and locks the user access privilege can be revealed.

Using a highly specific “lock and key” fluorescent Cys probe, we confirmed that targeting Cys metabolism to deplete intracellular Cys is a more potent strategy to sensitize cancer cells to chemotherapies.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

“Lock ‘Em Up . . .” but Where’s the Key? Transformative Drama with Incarcerated Youth
A research study doing applied theatre with youth at an Alberta, Canada young offender facility, asks: How can participatory drama contribute to the education of incarcerated youth to avoid future negative outcomes of their “at-risk” behaviours?
