Abstract

Eucaryotic endoplasmic reticulum and bacterial inner cell membranes use strikingly similar mechanisms to transport proteins from one cellular compartment to another. Using a mammalian linked transcription-translation system, we show here that canine pancreatic microsomes accurately cleave off the signal sequence of beta-lactamase, a secreted bacterial protein. We suggest that the apparent differences between bacterial and eukaryotic protein transport may involve only minor modulations of a profoundly conserved mechanism.
