+== Publication Abstract from PubMed ==
+Chloroplasts protein precursors translated in the cytosol traverse the membranes to reach their intended destination with the help of translocon complexes called translocon at the outer envelope of chloroplasts and translocon at the inner envelope of chloroplasts (TIC), respectively. Two components of the TIC translocon, Tic110 and Tic40, which combine with Hsp93 (ClpC), are involved in protein translocation across the inner membrane into the stroma. The C-terminal NP-repeat domain of Tic40 (Tic40-NP) is homologous to the DP-repeat domain of co-chaperones Hsp70-interacting and Hsp70/Hsp90-organizing proteins. Interaction of Tic40-NP and Hsp93 stimulates ATP hydrolysis of Hsp93, but the hydrolysis is abolished in both N320A and N329A mutants of Tic40-NP. Here, we determined the nuclear magnetic resonance structure of Tic40-NP, which mainly consists of five alpha-helices stabilized by two hydrophobic cores. In addition, chemical shift perturbation results suggested that some residues at alpha1 and alpha5, as well as residues Asn320 and Asn329, cause conformational change on the two mutants, which may subsequently affect their binding to Hsp93. We provide valuable information for further investigating how Tic40-NP interacts with Hsp93.
