Biogenesis of Porin of the Outer Mitochondrial Membrane Involves an Import Pathway via Receptors and the General Import Pore of the TOM Complex
Download2001
Nargang, F. E., Pfanner, N., Neupert, W., Blachly-Dyson, E., Forte, M., Krimmer, T., Ryan, M. T., Kassenbrock, K., Rapaport, D., Douglas, M. G., Meisinger, C.
Abstract: Porin, also termed the voltage-dependent anion channel, is the most abundant protein of the mitochondrial outer membrane. The process of import and assembly of the protein is known to be dependent on the surface receptor Tom20, but the requirement for other mitochondrial proteins...

Reconstituted TOM core complex and Tim9/Tim10 complex of mitochondria are sufficient for translocation of the ADP/ATP carrier across membranes

Habib, S.J., Panneels, V., Vasiljev, A., Prokisch, H., Nussberger, S., Neupert, W., Sinning, I., Nargang, F.E., Ahting, U., Rapaport, D., Go, N.E., Kozany, C.
Precursor proteins of the solute carrier family and of channel forming Tim components are imported into mitochondria in two main steps. First, they are translocated through the TOM complex in the outer membrane, a process assisted by the Tim9/Tim10 complex. They are passed on to the TIM22...

Structural requirements of Tom40 for assembly into preexisting TOM complexes of mitochondria
Download2001
Neupert, W., Käser, M., Taylor, R.D., Nargang, F.E., Rapaport, D., Langer, T.
Tom40 is the major subunit of the translocase of the outer mitochondrial membrane (the TOM complex). To study the assembly pathway of Tom40, we have followed the integration of the protein into the TOM complex in vitro and in vivo using wild-type and altered versions of the Neurospora crassa...

The Oxa2 protein of Neurospora crassa plays a critical role in the biogenesis of cytochrome oxidase and defines a ubiquitous subbranch of the Oxa1/YidC/Alb3 protein family

Herrmann, J.M., Nargang, F.E., Neupert, W., Funes, S.
Proteins of the Oxa1/YidC/Alb3 family mediate the insertion of proteins into membranes of mitochondria, bacteria, and chloroplasts. Here we report the identification of a second gene of the Oxa1/YidC/Alb3 family in the genome of Neurospora crassa, which we have named oxa2. Its gene product, Oxa2,...

The TOM core complex: the general protein import pore of the outer membrane of mitochondria

Thun, C., Neupert, W., Hegerl, R., Nussberger, S., Typke, D., Ahting, U., Nargang, F. E.
Abstract: Translocation of nuclear-encoded preproteins across the outer membrane of mitochondria is mediated by the multicomponent transmembrane TOM complex. We have isolated the TOM core complex of Neurospora crassa by removing the receptors Tom70 and Tom20 from the isolated TOM holo complex by...
