Export of the periplasmic maltose-binding protein of Escherichia coli.

Journal of bioenergetics and biomembranes - 1 Jun 1990

Bassford P J

Abstract excerpt

The export of the maltose-binding protein (MBP), the malE gene product, to the periplasm of Escherichia coli cells has been extensively investigated. The isolation of strains synthesizing MalE-LacZ hybrid proteins led to a novel genetic selection for mutants that accumulate export-defective precursor MBP (preMBP) in the cytoplasm. The export defects were subsequently shown to result from alterations in the MBP...
