UrduA new study on rubisco, a photosynthetic enzyme thought to be the most abundant protein on the planet, shows that proteins can change their structural arrangement with surprising ease. The findings reveal the possibility that many of the proteins we thought we knew actually exist in other, unknown shapes.

Researchers create a breakthrough tool for superfast molecular movies
Certain biological events, such as proteins changing their shapes to perform some functions, occur so quickly that current methods of molecular imaging cannot capture them. Now, a research team has created a machine-learning technique that can “fill in” missing data needed to document proteins in action in time scales of a few quadrillionths of a second.
Making molecular movies of a biological process of energy conversion
An international team of scientists have observed a sunlight-fueled atomic “pump” working in the cells of a marine bacterium. The imaging was done with an advanced technique called time-resolved serial femtosecond crystallography.
Supercomputing Aids Scientists Seeking Therapies for Deadly Bacterial Disease
A team of scientists led by Abhishek Singharoy at Arizona State University used the Summit supercomputer at the Oak Ridge Leadership Computing Facility to simulate the structure of a possible drug target for the bacterium that causes rabbit fever.
