Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Method for judging seismic stability state of soil slopes

open access: yesYantu gongcheng xuebao, 2018
Based on the strength reduction FEM, the method for judging the stability state of soil slopes under earthquake action is analyzed. The length ratio of equivalent plastic strain zone in the slope is defined, and the corresponding relationship between the

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Iteratively Decoded Irregular Variable Length Coding and Trellis Coded Modulation

open access: yes, 2007
In this paper we propose a novel Irregular Variable Length Coding (IrVLC) scheme for near-capacity joint source and channel coding. We employ a number of Variable Length Coding (VLC) component codebooks having different coding rates for encoding ...

Simulation and structural optimization of flat double-P type radiant tubes based on the orthogonal method

open access: yes工程科学学报, 2017
The effects of structural dimensions such as central tube equivalent radius, branch tube equivalent radius, tube spacing, and tube length on the performance of a flat double-P type radiant tube were studied in this paper. The structural dimensions of the

Self-Intersection Numbers of Length-Equivalent Curves on Surfaces [PDF]

open access: yesExperimental Mathematics, 2014
Two free homotopy classes of closed curves in an orientable surface with negative Euler characteristic are said to be length equivalent if for any hyperbolic structure on the surface, the length of the geodesic in one class is equal to the length of the geodesic in the other class.

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS 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.

Length-Lex Open Constraints

open access: yes, 2018
Open constraints were introduced to model the many industrial applications in which a task can be handled by several resources. Open constraints are unique because the set of variables over which the the constraint is defined is a set-variable. Regin and

Numerical Modelling Study of Subsurface Drainage of Permeable Friction Course Considering Road Geometric Designs

open access: yesApplied Sciences, 2023
This study aimed to evaluate the subsurface drainage of a permeable friction course (PFC) via two-dimensional finite element analysis. To achieve the scope, PFCs with equivalent water flow paths of length values of 10, 15, 20, and 30 m and slope values ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
