This photo depicts a close-up of a small crystal of protein from Mycobacterium tuberculosis mounted on a high intensity x-ray diffraction data collection facility at Texas A&M. The 0.2 mm crystal is being cooled by a stream of nitrogen at -173°C. It is being held between the high-intensity x-ray beam from the nozzle on the left side of the picture and a CCD detector. Diffracted x-rays from the crystal will be used to determine the three-dimensional structure of the TB protein which will be used to explore its function and design new drugs.
