3.A.9.1.1
Chloroplast envelope protein translocase (CEPT); outer membrane complex. The Tic20-like protein (acc # AUO68237.1; 413 aas, 6 TMSs in a 1 TMS (N-terminal) + 5 TMSs (C-terminal)), of the lower brown alga, Saccharina japonica, has been characterized (Chen et al. 2019).  The melon necrotic spot virus coat protein exploits the common Toc/Tom import systems to enter both mitochondria and chloroplasts (Sáiz-Bonilla et al. 2023).
