Vesicle Inducing Protein in Plastids (Vipp1) is one of the essential proteins for thylakoid biogenesis in both chloroplasts and cyanobacteria. However, the molecular structure and the exact function of Vipp1 is not yet known. Using cryo-electron tomography and sub-tomogram averaging, we showed that CrVipp1 rods can engulf liposome membranes containing phosphatidylinositol-4-phosphate (PI4P). Using single-particle cryo-electron microscopy, we solved the molecular structure of SynVipp1. We found that SynVipp1 predominantly assembled into barrel-like rings.
