7.4.2.4 | ATP + H2O | two distinct protein translocation machineries at the outer and inner chloroplast envelope membrane participate in the import of precursor proteins. The translocon at the outer envelope membrane of the chloroplast, Toc, mediates the initial binding of the cytosolic precursor proteins at the chloroplast surface and their subsequent ATP/GTP-dependent translocation across the outer membrane. Protein translocation across the inner membrane is mediated by the translocon at the inner envelope membrane of the chloroplast, Tic, and is driven by ATP hydrolysis in the stroma | Pisum sativum | ADP + phosphate | - |
