| Sumario: | HIV-1 envelope glycoprotein (Env) mediates the fusion of viral and target cell membranes and is a major target for HIV vaccine development. Here, the authors determine the NMR structure of a bicelle incorporated Env segment comprising the transmembrane domain (TMD) and a portion of the cytoplasmic tail (CT), and show that the CT folds into membrane attached amphipathic helices that wrap around the TMD thereby forming a support baseplate for the rest of Env, and they also provide insights into the dynamic coupling across the TMD between the ectodomain and CT. |
