    ..Both TIM complexes display a native molecular mass of 110 kDa. We suggest that the structural organization of TIM23.17 preprotein translocases is conserved from low to high eukaryotes. ..

    ..These assays thus demonstrated the 18.1, 21.9, and 45 kDa proteins to be the translocator components of the rat mitochondrial inner membrane and, therefore, the functional homologues of Tim17, Tim23, and Tim44, respectively. ..
