Requirements for a conservative protein translocation pathway in chloroplasts

The chloroplast inner envelope translocon subunit Tic110 is imported via a soluble stromal translocation intermediate. In this study an in- organellar import system is established which allows for an accumulation of this intermediate in order to analyze its requirements for reexport. All results demonstrate that the re-export of Tic110 from the soluble intermediate stage into the inner envelope requires ATP hydrolysis, which cannot be replaced by other NTPs. Furthermore, the molecular chaperone Hsp93 seems prominently involved in the reexport pathway of Tic110, because other stromal intermediates like that of the oxygen evolving complex subunit OE33 (iOE33) en route to the thylakoid lumen interacts preferentially with Hsp70.
