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 ...

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.

Measurements of microwave reflection properties of early-age concrete and mortar specimens
, 2014 Measurement and monitoring results on reflection properties of concrete and mortar cubic specimens are presented in this paper. The results were obtained by using a sweeping microwave frequency over entire X-band (8.2 – 12.4 GHz).

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 ...

Measures on monotone properties of graphs
Discrete Applied Mathematics, 2002 A monotone property \({\mathcal P}\) is one that is closed under isomorphism and under taking subgraphs. The graphs of \({\mathcal P}\) with vertex set \([n]\) will be denoted by \({\mathcal P}_n\). Various enumeration measures of monotone properties are investigated. In particular, results on the speed of \({\mathcal P}\), which is \(|{\mathcal P}_n|\)

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 ...
