Pressure is a fundamental thermodynamic parameter controlling the behavior of biological macromolecules. In many cases pressure alters molecular shape and therefore also the biological function.
CHESS is well known for experimental versatility and method/instrumentation development and we have a user base that is interested in anoxic capabilities. From the gut microbiome to the depths of the ocean, life has evolved to thrive in the absence of oxygen. In fact, it is not hyperbole to say that life as we know it would not exist without the oxygen sensitive metalloenzymes that we all rely on. A method to allow structural study of these systems will open many avenues of research, and CHSX beamline 7A1 is the only beamline in the world known to offer this capability.
