We need to talk about nanowires

For nearly two decades, biological electron transfer research was dominated by the hypothesis that Geobacter pili form conductive nanowires. Cryo-electron microscopy has now revealed their structure. Not everybody is happy.

Shewanella– You don’t know the power of the dark side

Shewanella is an environmental bacterium capable of breathing more compounds than any other organism identified on Earth. Many of these substrates are found naturally in insoluble oxide minerals, meaning they must take electrons from central metabolism and move them outside the cell. 

Here I will describe surprising functions for extracellular electron transfer proteins in what might be a respiration over-drive system and a multiheme cytochrome that is a receptor for bacteriophage.
