The mitochondrial import protein Mim1 promotes biogenesis of multispanning outer membrane proteins
The mitochondrial outer membrane contains translocase complexes for the import of precursor proteins. The translocase of the outer membrane complex functions as a general preprotein entry gate, whereas the sorting and assembly machinery complex mediates membrane insertion of β-barrel proteins of the outer membrane. Several α-helical outer membrane proteins are known to carry multiple transmembr...
متن کاملA crucial role for Mim2 in the biogenesis of mitochondrial outer membrane proteins.
Most of the mitochondrial outer membrane (MOM) proteins contain helical transmembrane domains. Some of the single-span proteins and all known multiple-span proteins are inserted into the membrane in a pathway that depends on the MOM protein Mitochondrial Import 1 (Mim1). So far it has been unknown whether additional proteins are required for this process. Here, we describe the identification an...
متن کاملRole of mitochondrial inner membrane organizing system in protein biogenesis of the mitochondrial outer membrane
Mitochondria contain two membranes, the outer membrane and the inner membrane with folded cristae. The mitochondrial inner membrane organizing system (MINOS) is a large protein complex required for maintaining inner membrane architecture. MINOS interacts with both preprotein transport machineries of the outer membrane, the translocase of the outer membrane (TOM) and the sorting and assembly mac...
متن کاملBiogenesis of mitochondrial proteins.
Numerous components have been identified that participate at various stages in the biogenesis of mitochondria. For many of these components, their specific functions have recently been defined through detailed investigations of the molecular mechanisms underlying protein targeting, translocation across the mitochondrial outer and inner membranes, membrane insertion, suborganellar sorting, and p...
متن کاملBiogenesis of the mitochondrial DNA inheritance machinery in the mitochondrial outer membrane of Trypanosoma brucei
Mitochondria cannot form de novo but require mechanisms that mediate their inheritance to daughter cells. The parasitic protozoan Trypanosoma brucei has a single mitochondrion with a single-unit genome that is physically connected across the two mitochondrial membranes with the basal body of the flagellum. This connection, termed the tripartite attachment complex (TAC), is essential for the seg...
