摘要：
The process of mitochondrial protein import has been studied for many years. Despite this attention, many processes associated with mitochondrial biogenesis are poorly understood. Insight into one of these processes, assembly of beta-barrel proteins into the mitochondrial outer membrane, will be discussed. This review focuses on recent data that suggest that assembly of beta-barrel proteins into the outer mitochondrial membrane is dependent on a newly identified protein complex termed the sorting and assembly machinery (SAM complex). Members of the SAM complex have been identified in both eukaryotic and prokaryotic organisms, suggesting that the process of beta-barrel assembly into membranes has been conserved through evolution.
