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.

Webb1 juni 2010 · The involvement of thioredoxins in protein import into chloroplasts has also been suggested: Bartsch et al. [91] characterized Tic55 together with PAO and Ptc52 (two other members of the non-heme oxygenases family) as thioredoxin targets in the inner envelope membrane of chloroplasts. WebbProtein import into chloroplasts is a highly regulated process. The activity of the major import receptors is regulated by protein phosphorylation, as well as by GTP binding and … Webb1 feb. 2013 · Protein translocation across biological membranes requires supramolecular complexes, called translocons.
