Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

An initial stability of Kirchhoff plates supported on boundary and resting on internal supports is analysed in this paper. The internal supports are understood to be part of a plate surface or a line belonging to the plate.

On Numerical Solutions of Boundary Integral Equations
Elastic boundary value problems can be formulated in the form of boundary integral equations, whose numerical solutions are obtained by boundary element methods. This paper deals with error estimation of boundary element solutions. Especially, approximate solutions obtained by constant or linear elements are investigated for cases of two-dimensional ...

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 ...

Wavelet Galerkin Algorithms for Boundary Integral Equations [PDF]
The implementation of a fast, wavelet-based Galerkin discretization of second kind integral equations on piecewise smooth surfaces $\Gamma\subset \IR^3$ is described. It allows meshes consisting of triangles as well as quadrilaterals.

Structural and biochemical analysis of a B12 superbinder
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.

Piecewise Polynomial Collocation for Boundary Integral Equations [PDF]
This paper considers the numerical solution of boundary integral equations of the second kind for Laplace’s equation $\Delta u = 0$ on connected regions D in ${\bf R}^3 $ with boundary S. The boundary S is allowed to be smooth or piecewise smooth, and we let $\{ \Delta _K |1 \leq K \leq N\} $ be a triangulation of S. The numerical method is collocation

Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

On singular integral equations with variable limits of integration
The wide range of problems of mathematical physics is reduced to a special Volterra integral equation of the second kind or to integral equations with variable limits of integration.
