The peripheral membrane subunits of the SAM complex function codependently in mitochondrial outer membrane biogenesis.

Abstract

The sorting and assembly machinery (SAM) complex functions in the assembly of beta-barrel proteins into the mitochondrial outer membrane. It is related to the Omp85/YaeT machinery in bacterial outer membranes, but the eukaryotic SAM complex is distinguished by two peripheral subunits, Sam37 and Sam35, that sit on the cytosolic face of the complex. The… (More)
