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

Simultaneous rational approximation of a function and its derivatives in the complex plane
Journal of Approximation Theory, 1985 Some aspects of simultaneous rational approximation of a function f(z) and its derivatives on the unit circle are investigated. The function f(z) is assumed to be analytic in some annulus containing the unit circle, and given a nonnegative integer \(\ell\), \(\| f\| =\max \{\| f^{(j)}\|_{p,1}:0\leq j\leq \ell \},\) where \(\| \cdot \|_{p,1}\) is the ...

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Weighted rational approximation in the complex plane
, 1998 . Given a triple (G W ) of an open bounded set G in the complex plane, a weight function W (z) which is analytic and di erent from zero in G, and a number with 0 1, we consider the problem of locally uniform rational approximation of any function f(z)

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Harmonic Version of Jackson's Theorem in the Complex Plane [PDF]
, 1997 The classical Jackson theorem concerning polynomial approximation of functions on [−1, 1] is generalized to the case of approximation of functions given on a piecewise smooth arc in the complex plane by harmonic ...

Mathematical and Computational ApplicationsA permanent gravity wave propagating on deep water is a classic mathematical problem. However, the Fourier series approximation (FSA) based on the physical plane was examined to be valid for almost waves at all depths.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers
Molecular Oncology, EarlyView.The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Outer Approximation Algorithms for DC Programs and Beyond [PDF]
, 2008 We consider the well-known Canonical DC (CDC) optimization problem, relying on an alternative equivalent formulation based on a polar characterization of the constraint, and a novel generalization of this problem, which we name Single Reverse Polar ...
