Escherichia coli SecB stimulates export without maintaining export competence of ribose-binding protein signal sequence mutants.

Journal of bacteriology - 1 Oct 1996

Francetic O, Kumamoto C A

Abstract excerpt

Ribose-binding protein (RBP) is exported to the periplasm of Escherichia coli via the general export pathway. An rbsB-lacZ gene fusion was constructed and used to select mutants defective in RBP export. The spontaneous Lac+ mutants isolated in this selection contained either single-amino-acid substitutions or a deletion of the RBP signal sequence. Intact rbsB genes containing eight different point mutations in...
