Conservation of components of the Escherichia coli export machinery in prokaryotes

FEMS Microbiol Lett. 1991 May 15;64(2-3):195-9. doi: 10.1016/0378-1097(91)90594-z.

Abstract

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.
