Protein import into chloroplasts

WebbDuring the endosymbiotic evolution of chloroplasts, the vast majority of genes from the original cyanobacterial endosymbiont were transferred to the host cell nucleus. Chloroplast biogenesis therefore requires the import of nucleus-encoded proteins from their site of synthesis in the cytosol. WebbMost models of chloroplast protein import suggest that the protein conducing channel across the outer envelope is a beta-barrel protein that is characteristic of bacterial outer membranes and the outer membrane of chloroplasts and mitochondria.
