Generalized domination and efficient domination in graphs
Discrete Mathematics, 1996 The closed neighbourhood of a vertex \(v\) of a graph \(G\) is the set consisting of \(v\) and of all vertices adjacent to \(v\) in \(G\). A function \(f\) which maps the vertex set \(V(G)\) of \(G\) onto a subset \(Y\) of the set of real numbers is called \(Y\)-dominating in \(G\), if the sum of its values over the closed neighbourhood of each vertex \

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.

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 ...

Species richness, composition, and dominance of core and climate relicts of African miombo woodlands
EcosphereThe miombo woodlands, which span about 10% of the African continent, are essential for the ecosystem services they provide. These woodlands are mainly dominated by the genera Julbernardia, Isoberlinia, and Brachystegia.

Prospecting the protein design landscape
FEBS Letters, EarlyView.This review outlines the current state of various protein design approaches. We discuss the current possibilities enabled by recently released tools, highlight future avenues to pursue in protein design, and underscore the crucial role of key databases and resources for successful protein design workflows.

Testing for Mobility Dominance [PDF]
This paper proposes tests for stochastic dominance in mobility based on the empirical likelihood ratio. Two views of mobility are considered, either based on measures of absolute mobility or on transition matrices.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability
FEBS Letters, EarlyView.Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Stochastic Dominance Analysis of iShares [PDF]
Country indices as represented by iShares exhibit non-normal return distributions with both skewness and kurtosis. Davidson and Duclos (2000) and Memmel (2003) provide procedures for determining the statistical significance of stochastic dominance ...
