Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Pollutant particles emission has been a major source of worry for many years due to their negative health impacts. For health risk assessment, it is critical to understand how to assess pollutant particles transportation and deposition (TD) in human lung

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 ...

THE minerals found in clays and soil colloids are usually considered to be plate-shaped and to have layer lattices built up from sheets of silicon – oxygen tetrahedra. This may be true in the majority of cases, but rod- or needle-shaped particles can also occur and should not be overlooked. Their presence may be due to one of the following two reasons.

Structural and biochemical analysis of a B12 superbinder
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.

ON THE DETERMINATION OF THE SHAPE-TYPE OF PARTICLES
Based on observations on similar-looking randomly deformed particles inference is made about the original common shape-type of these particles by means of statistical tests.

Internal erosion is one of the main causes of seepage damage in natural sediments or geotechnical structures. In the seepage process, particle shape is an important factor affecting the development of erosion in soil.

Shape-Directed Microspinners Powered by Ultrasound
The propulsion of micro- and nanoparticles using ultrasound is an attractive strategy for the remote manipulation of colloidal matter using biocompatible energy inputs. However, the physical mechanisms underlying acoustic propulsion are poorly understood,

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 ...
