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. >>> See more animations and explanation >>>	Geobacter pili: surprising function. Y Gu, V Srikanth, AI Salazar-Morales, R Jain, JP O'Brien, SM Yi, RK Soni, FA Samatey, SE Yalcin, NS Malvankar. Nature 2021 doi: 10.1038/s41586-021-03857-w Geobacter pili were long thought to be electrically conductive protein nanowires composed of PilA-N. Nanowires are crucial to the energy metabolism of bacteria flourishing in oxygen-deprived environments. To everyone's surprise, in 2019, the long-studied nanowires were found to be linear polymers of multi-heme cytochromes, not pili. The first cryo-EM structure of pili (2021) reveals a filament made of dimers of PilA-N and PilA-C, shown. Electrical conductivity of pili is much lower than that of cytochrome nanowires. Evidence suggests that PilA-NC filaments are periplasmic pseudopili crucial for exporting cytochrome nanowires onto the cell surface, rather than the pili serving as nanowires themselves. >>> Visit I3DC Interactive Visualizations >>>	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. >>> See Examples and Get Instructions >>>
