Assembly of Protein‐DNA Framework Nanostructures: Structurally Defining Protein‐DNA Interfaces With Aptamer

Angewandte Chemie, EarlyView.
Rationally designed DNA multivalent aptamers direct specific protein binding to drive self‐assembly into protein‐DNA frameworks (PDFs). Structurally defined protein‐aptamer interfaces organize proteins into triangles, linear and ladderlike chains, and periodic two‐dimensional arrays, enabling precise control over orientation, connectivity, and overall ...

When the River Runs Low: Heterogeneous Impacts of Transportation Disruptions on Local Grain Basis

Agribusiness, EarlyView.
ABSTRACT A substantial share of U.S. soybean and corn exports from the Midwest moves by barge along the Mississippi River system to export terminals in the Louisiana Gulf. Transportation costs between Midwestern grain elevators and export terminals create a wedge between prices at these locations, and shocks to these costs are partially passed on to ...
