About this image
Bacteria float with nano-balloons.

ST Huber, D Terwiel, WH Evers, D Maresca, AJ Jakobi. Preprint 2022 doi: 10.1101/2022.05.08.489936
Many kinds of bacteria and archaea control their buoyancy to move to optimal positions in liquid environments. They do this by making nano-compartments called "gas vesicles", long "pipes" with closed ends filled with gases. In 2022, gas vesicle structure was solved, revealing self-assembling thin-walled cylinders of remarkable strength with gas-permeable pores and water-repelling (hydrophobic) interiors. Building on this structural knowledge, gas vesicles are being engineered to serve as biosensors that report via ultrasound.

About this image
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.

About this image
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.
