The mitochondrial protein import system. The mitochondrial protein import system consists of seven machineries, including the translocase of the outer mitochondrial membrane (TOMM) machinery, mitochondrial import machinery (MIM), sorting and assembly machinery (SAM), mitochondrial intermembrane space import and assembly machinery (MIA), translocase of the inner mitochondrial membrane 23 (TIMM 23) machinery, translocase of the inner mitochondrial membrane 22 (TIMM 22) machinery, and a presequence-associated motor (PAM).
