Structure of Diacylglycerol Kinase (IMAGE) Vanderbilt University Medical Center Caption Surface-filled representation of diacylglycerol kinase. The "porch-like" structure of the enzyme is highlighted, and the substrate diacylglycerol is depicted bound to the active site. Investigators at the Vanderbilt Center for Structural Biology used NMR methods to determine the structure of diacylglycerol kinase, the largest membrane-spanning protein studied by NMR to date.
