Welcome to the second day of the New Year! Like tasty sliders, these short news stories should get the juices flowing for big developments in 2020. Electric Proteins Dr. Stuart Lindsey at Arizona State University is an expert in single-molecule dynamics in biomolecules. Older methods of observing protein structure, such as X-ray crystallography, only gave single snapshots of the highly dynamic world, he says, where proteins rapidly change conformations and interact in complex ways. Electron transport has been well known in the cases of photosynthesis and metabolism. But a few years ago, his team was astonished to find that a run-of-the-mill protein conducted electricity. The protein was acting like a wire! Further observations revealed that all proteins conduct electricity — even the ones that had “weren’t designed to do this”—…

When a city starts out with a major energy deficit, there are two changes that should be made: to be really, and I mean really efficient at recycling the critical resource, or to buy more energy. What about in biology? Cells are like cities, right? Out of Balance We already know from a previous post (“The Mystery of Energy Metabolism”) that the cell has an energy budget that is out of balance based solely on biosynthesis and use of ATP. It is in a predicament. It has an extreme shortfall in ATP in its balance sheet, needing six ATP just to make one. ATP is a high energy molecule. All that energy has to be loaded into the molecule during its synthesis by using up other ATP molecules. If chemical A is…
