A Force-Generating Machine in the Plant’s Power House: A Pulling AAA ATPase Motor Drives Protein Translocation into Chloroplasts

Most chloroplast proteins are encoded by the nuclear genome and synthesized on cytosolic ribosomes. N-terminal transit peptides serve as targeting sequences to direct precursors of chloroplast proteins to receptors on the chloroplast surface. These receptors are part of the translocase of the outer envelope, the TOC complex, and transport precursor proteins in a GTP-dependent reaction […]
