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.

Two-way interplays between capital buffers, credit and output: evidence from French banks [PDF]
We assess the extent to which capital buffers (the capital banks hold in excess of the regulatory minimum) exacerbate rather than reduce the cyclical behavior of credit.

Avian response to conservation buffers in agricultural landscapes during winter
Wildlife Society Bulletin, 2014 Native herbaceous vegetation cover along row‐crop field edges (i.e., field buffers) increases breeding densities of many bird species. However, the effect of field buffers on bird species during the non‐breeding season is less understood.

Buffers of Milk and Buffer Value
Journal of Dairy Science, 1927 Since buffers are considered as substances which, by their presence in solution, increase the amount of alkali or acid that must be added to catme unit change in pH, the question of their occurrence in milk would be important. Clark (1) gives the following with regard to buffers: "By buffer action, we mean the ability of a solution to resist change in ...

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 ...

COST EFFECTIVENESS OF NUTRIENT MANAGEMENT AND BUFFERS: COMPARISONS OF FOUR SPATIAL SCENARIOS [PDF]
Policymakers are seeking cost effective methods to reduce nutrient pollution from agriculture. Predicted costs and pollution reductions from nutrient management and buffers are evaluated under four spatial scenarios describing a watershed.
