FGAMS Expressed (IMAGE) Penn State Caption The enzyme called FGAMS (red) is expressed in human neuron-like cells, which suggests its involvement in the synthesis of purines, a component of DNA involved in many other cellular and metabolic processes. Using a new method to create synthetic neurons from a readily available cell line, a new study explores the role of FGAMS in creating a multi-enzyme complex called the purinosome, which enables faster production of purines.
