In the August 4, 2013 issue of Nature & Structural Molecular Biology researchers from The Wistar Institute, the University of Pennsylvania, and the University of Bergen published the structure of an enzyme called NatA, which has a role in modifying proteins and is found in increased amounts in cancer cells. Their findings, they believe, will help in creating an inhibitor against NatA that may curb the spread of cancerous cells. What follows is a brief animation of the enzyme's structure and the shape changes that occur to the enzyme when another molecule binds to it. An overall view of the NatA complex structure. The complex is shown rotating 360° on the y-axis followed by 360° on the x-axis. The NatA active site (Naa10p) changes shape upon binding to a site called Naa15p. This movie shows a morph that highlights the change in the position of several key residues. The morph is shown twice, once with acetyl CoA bound to Naa10p and again with an inhibitor bound to Naa10p.
