Conservation of components of the Escherichia coli export machinery in prokaryotes.
The SecA and SecB proteins are involved in protein translocation in Escherichia coli. Immunoblot analysis was used to investigate the possible conservation of these proteins in prokaryotes. Cross-reacting proteins were detected in all other Enterobacteriaceae tested, but not in microorganisms more distantly related from Escherichia coli.
