Figure 9: Hypothetical model for co-translational membrane protein insertion in yeast mitochondria.
From: Organization of the mitochondrial translation machinery studied in situ by cryoelectron tomography
The inner membrane protein Mba1 aligns the mitochondrial peptide exit tunnel (dashed lines) with the membrane insertion machinery (black box) and supports the transfer of the very hydrophobic mitochondrial nascent peptides (red line) towards the membrane to facilitate their fast and reliable insertion.
