CAO, Tic55, and Ptc52 establish distinct Tic subcomplexes. (A) 125I-APDP crosslinking of plastid-envelope proteins that interact with CAO, Tic55, and Ptc52, respectively, after import. (B) Western blot of CAO, Tic55, and Ptc52 as well as Toc75 and Oep16 in the different recovered inner envelope membrane complexes. “Total” refers to a blot that was probed with a mixed CAO, Ptc52, and Tic55 antiserum together. Note the differential interaction of CAO and Tic55 with Toc75 and that of Ptc52 with Oep16.
