Researchers Witness Assembly of Molecules Critical to Protein Function


June 17, 2008

a four iron-four sulfur cluster Iron-sulfur clusters are critical to life on earth. They are necessary for protein function in cellular processes, such as respiration in humans and other organisms and photosynthesis by plants. A Virginia Tech research group has isolated proteins responsible for the iron-sulfur cluster assembly process and witnessed the necessary protein interactions in vivo--within a cell. Full Story
