Structure of Key Enzyme in Plague Bacterium Found

Caption: Ribbon rendering of the structure of AC-IV in Yersina pestis as determined at NIST. The enzyme is a dimer (two identical subunits around a vertical axis), and each of the two subunits forms a central barrel made of eight strands surrounded by short helices. The active site is believed to lie inside the barrel.
