Protein Domain : Chloroplast envelope protein translocase, IAP75 IPR005689

Type	Family
Description	Chloroplast function requires the import of nuclear encoded proteins from the cytoplasm across the chloroplast double membrane. This is accompished by two protein complexes, the Toc complex located at the outer membrane and the Tic complex loacted at the inner membrane [ ]. The Toc complex recognises specific proteins by a cleavable N-terminal sequence and is primarily responsible for translocation through the outer membrane, while the Tic complex translocates the protein through the inner membrane.This entry represents Toc750, a core component of the Toc complex. This protein is deeply embedded in the outer membrane and forms the voltage-dependent translocation channel [ ]. Toc75 itself appears to be capable of at least some discrimination between substrate and non-substrate proteins, with recognition based on based on both conformational and electrostatic interactions.
