Everything a cell does, from dividing in two to migrating to a different part of the body, is controlled by enzymes that chemically modify other proteins in the cell. Researchers at Princeton University have devised a new mathematical technique to describe the behavior of many cellular enzymes. The approach, published February 13 in the journal Current Biology, will help researchers determine how genetic mutations change the behavior of these enzymes to cause a range of human diseases, including cancer. https://discovery.princeton.edu/2020/02/13/mathematical-model-reveals-behavior-of-cellular-enzymes/
