Abstract
The study of protein export has proceeded in parallel in eukaryotic and prokaryotic systems over the past 10 years. Much of the information on eukaryotic protein secretion has come from the detailed analysis of an in vitro system which appears faithfully to mimic the in vivo pathway. In prokaryotes much of the progress has come from in vivo analysis including genetic studies. The genetic studies have focussed both on the components of specific proteins which determine their localization and on the nature of cellular components which are part of the export process. There now exists a large collection of mutations in the signal sequences of bacterial envelope proteins. These have been accumulated using both in vivo selections and in vitro constructions. These mutations have confirmed many aspects of the original signal sequence hypothesis and have provided some insight into the important features of such sequences. Studies on signal sequence mutations have been recently reviewed (Michaelis and Beckwith 1982; Benson et al. 1985) and will not be covered in this article.
