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 ...

A Note On The Series Space |N ̅_p^θ |(μ)
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019 The series space$\left\vert \bar{N}_{p}^{\theta }\right\vert\left( \mu \right) $has recently been introduced and studied by Gökçe and Sarıgöl [1]. Themain purpose of this paper is to determine the $\alpha-$,$\beta-$and$\gamma$_duals of the space and to ...

Revista Matemática Complutense, 1991 Bekanntlich heißt ein Raum \(E\) von komplexwertigen Folgen \(x=(x_ n)\) solid, wenn gilt: \(x\in E\;\&\;| y_ n|\leq| x_ n|\), \((n\in\mathbb{N})\Rightarrow y\in E\). Diese Eigenschaft läßt sich auf vektorwertige Folgenräume in verschiedene Richtungen verallgemeinern. Für einen normierten Raum \(X\) bezeichne \(s(X)\) den Raum aller Folgen \(x=(x_ n)\)

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.

International Journal of Mathematics and Mathematical Sciences, 1995 In this paper we define the space co(Δ)={x=(xk)/xk−kk−1→0(k→∞),xo=0,xk∈ℂ} and compute its duals (Continuous dual, β-dual and N-dual) The aim of this paper is to give same results about matrix mapping of co(Δ) into other sequence spaces including the ...

Functional Sequence in Norm Space
Formalized Mathematics, 2020 Summary In this article, we formalize in Mizar [1], [2] functional sequences and basic operations on functional sequences in norm space based on [5]. In the first section, we define functional sequence in norm space. In the second section, we define pointwise convergence and prove some related theorems.

Grand Lebesgue sequence spaces
, 2018 We introduce grand Lebesgue sequence spaces and study various operators of harmonic analysis in these spaces, e.g., maximal, convolution, Hardy, Hilbert, and fractional operators, among others.

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 ...
