Mode of action of Oxa1p and positively charged TM domains. (A) Oxa1p could allow the membrane insertion of charged or less hydrophobic TM domains (e.g., first TM helix of Cox2p) by sandwiching them until they reach stable integration within the oligomeric complex (Cox complex). (B) Positively charged TM domain (e.g., Cyt1p) could be coinserted with a negatively charged one (e.g., first TM helix of Cox2p).
