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 ...

Modelling Of The Thermal Behavior Of Walls And Floors In Contact With The Ground [PDF]
, 2012 One of the most complex configuration to model in detail, both in the dynamic simulation of buildings and in the analytical quasi steady-state calculations, is the thermal dispersion through the walls and the floor in contact with the ground. The problem

Electronic Journal of Differential Equations, 2017 In this article, by using variational method, we study the existence of a positive ground state solution for the Schr\"odinger-Poisson system $$\displaylines{ -\Delta u+V(x)u+K(x)\phi u=f(x,u),\quad x\in\mathbb{R}^3,\cr -\Delta\phi=K(x)u^2,\quad x\in\

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.

Multiple solutions for a fractional $(p,t)$-Laplacian system with logarithmic nonlinearities
Electronic Journal of Qualitative Theory of Differential EquationsThis paper is concerned with the existence and multiplicity of a ground state solution for a class of fractional $(p,t)$-type systems involving logarithmic nonlinearities with sign-changing coefficients, which are obtained by variational methods.

Advances in Mathematical Physics, 2018 In the present paper we study the existence of positive ground state solutions for the nonautonomous Schrödinger-Poisson system with competing potentials. Under some assumptions for the potentials we prove the existence of positive ground state solution.

FEBS Letters, EarlyView.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 ...

Positive ground state solutions to Schrodinger-Poisson systems with a negative non-local term
Electronic Journal of Differential Equations, 2015 In this article, we study the Schrodinger-Poisson system $$\displaylines{ -\Delta u+u-\lambda K(x)\phi(x)u=a(x)|u|^{p-1}u, \quad x\in\mathbb{R}^3, \cr -\Delta\phi=K(x)u^{2},\quad x\in\mathbb{R}^3, }$$ with $p\in(1,5)$. Assume that $a:\mathbb{R}^3\to

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
