SecB protein: a cytosolic export factor that associates with nascent exported proteins.

Journal of bioenergetics and biomembranes - 1 Jun 1990

Kumamoto C A

Abstract excerpt

Soluble factors participate in protein translocation across a variety of biological membranes. The Escherichia coli soluble protein SecB (the product of the secB gene) is involved in the export of periplasmic and outer membrane proteins. The isolation of secB mutations permitted the demonstration that SecB is required for rapid and efficient export of certain proteins. Consistent with the results of these genetic...
