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.

Specialization, Factor Accumulation and Development [PDF]
The Heckscher-Ohlin theory links specialization of production to relative factor endowments. Endowments are the result of accumulation in response to economic in-centives. Taking this into account allows us to reconcile wildly di¤erent predictions in the

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 ...

Control of expression of the I factor, a LINE-like transposable element in Drosophila melanogaster [PDF]
, 1996 I factors are LINE-like transposable elements in the genome of Drosophila melanogaster. They normally transpose infrequently but are activated in the germline of female progeny of crosses between males of a strain that contains complete elements, an I or

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

\((r,r+1)\)-factorizations of \((d,d+1)\)-graphs
Discrete Mathematics, 2008 A \((d,d+1)\)-graph is a graph all of whose vertices have degrees in the set \([d,d+1]\). Such a graph is \textit{semiregular}. An \((r,r+1)\)-factorization of a graph \(G\) is a decomposition of \(G\) into \((r,r+1)\)-factors. For \(d\)-regular simple graph \(G\) we determine for which \(x\) and \(r\) \(G\) must have an \((r,r+1)\)-factorization with ...
