A novel LPS-dependent outer membrane-anchoring mechanism for T9SS substrates enables engineered enzyme display and whole-cell PET degradation in Cytophaga hutchinsonii

Synthetic and Systems Biotechnology
Robust surface display systems are crucial for engineering Gram-negative bacteria as whole-cell biocatalysts. In the efficient cellulose degrader Cytophaga hutchinsonii, cellulases are secreted by the Type IX Secretion System (T9SS), yet their mechanism ...

Development of a Landing Mechanism for Asteroids with Soft Surface

International Journal of Aerospace Engineering, 2013
A landing mechanism to an asteroid with soft surface is developed. It consists of three landing feet, landing legs, cardan element, damping element, equipment base, anchoring system, and so on.

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

FEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Optical Studies of Ordered Monomolecular Layers: Ab Initio Simulation and Experiment [PDF]

, 2009
Due to the general interest on the alignment effect of the surface-bound ultrathin layers, this thesis presents research of the investigation of anchoring properties for liquid crystal (LC) molecules adsorbed on a solid substrate, using dual polarization

Mussel-Inspired Anchoring of Polymer Loops That Provide Superior Surface Lubrication and Antifouling Properties

ACS Nano, 2016
We describe robustly anchored triblock copolymers that adopt loop conformations on surfaces and endow them with unprecedented lubricating and antifouling properties.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Genetic dissection of human ABCE1 in yeast reveals separable requirements for ribosome recycling and suppression of aberrant reinitiation

FEBS Open Bio, EarlyView.
Human ABCE1 cannot functionally replace its yeast ortholog. Yeast–human chimera analysis identified NBD1 as a major interspecies barrier. Genetic screening yielded hABCE1 revertants that rescue yeast viability but fail to suppress aberrant translation reinitiation in the 3′ UTR.

Simulation Analysis on Influential Factors of the Anchoring Force of Claw-Spine Attachment Device

International Journal of Aerospace Engineering
Asteroids have the characteristics of weak gravity, unknown surface topography and physical properties, and low cohesion of asteroid rocks, which make long-term attachment to an asteroid challenging.

Evaluating GenAI‐produced feedback on undergraduate bioscience essays against good higher education feedback practice

FEBS Open Bio, EarlyView.
This pilot study investigates the potential of Generative AI to provide formative feedback to students. ChatGPT was prompted to provide feedback on Year 1 Bioscience essays, which were evaluated against established good feedback practices. GenAI‐authored feedback had useful elements, but was limited in scope. GenAI may have potential to provide instant,
