Mitochondrial import pathways. First, nuclear-encoded mitochondrial proteins are imported by the TOM complex. Then, these proteins head to different pathways. Proteins with presequence are transported by the TIM23 complex and the PAM into the matrix. The intermembrane space localized proteins are imported via the MIA. β-barrel precursors of the outer membrane are transferred by the Tim9–Tim10 complex from TOM to SAM. Precursors of inner membrane carriers are inserted by the TIM22 complex into the inner membrane
