Abstract:
For a long time, it was generally assumed that the biogenesis of inner membrane proteins in Escherichia coli occurs spontaneously, and that only the translocation of large periplasmic domains requires the aid of a protein machinery, the Sec translocon. However, evidence obtained in recent years indicates that most, if not all, inner membrane proteins require the assistance of protein factors to reach their native conformation in the membrane. Here, we review and discuss recent advances in our understanding of the biogenesis of inner membrane proteins in E. coli.

Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
