Metal-Ligand Nano-Cages

This self-assembling structure has an interior cavity about 32 Å in diameter. It consists of 24 palladium ions, each of which is coordinated by 4 nitrogens, which are part of 48 dipyridylthiophene molecules. Such synthetic nano-spheres can be functionalized to create synthetic receptors and nanoreactors. Potential applications in sensing, catalysis, and drug delivery are being explored.

Structural flexibility of the periplasmic protein, FlgA, regulates flagellar P-ring assembly in Salmonella enterica.

H Matsunami, YH Yoon, VA Meshcheryakov, K Namba, FA Samatey. Scientific Reports 2016 doi: 10.1038/srep27399
A periplasmic flagellar chaperone protein, FlgA, is required for P-ring assembly in bacterial flagella of taxa such as Salmonella enterica or Escherichia coli. Here we present the open and closed crystal structures of FlgA from Salmonella enterica serovar Typhimurium, grown under different crystallization conditions. An intramolecular disulfide cross-linked form of FlgA caused a dominant negative effect on motility of the wild-type strain.

Make Your Own Electrostatic Potential Maps

Positive (+) and Negative (-) charges on the surface of a protein molecule play crucial roles in its interactions with other molecules, and hence in its functions. Electrostatic potential maps coloring the surface of a protein molecule are a popular way to visualize the distribution of surface charges. Easy to use free software is available to to create these surface maps. Above is an integral membrane potassium channel protein. One of its 4 identical chains is removed so you can see the Negative (-) protein surface contacting the 3 K+ ions.
