Proteins And The Chamber Of Doom

Indiana Jones isn't the only one who has great adventures, apparently proteins do also. Researchers have uncovered a a slippery tube that funnels proteins into a 'chamber of doom' where they are shredded and recycled into the building blocks of new proteins. The tube is part of the 26S proteasome, an enzyme that acts as the cell’s protein garbage disposal. As described by researchers from the Technion-Israel Institute of Technology and the University of Texas Health Science Center at San Antonio, the tube is a concentric stack of rings wrapped in molecular motors that speed the proteins toward the proteasome’s slicing and dicing core.
