Abstract
The Ml3 coat protein spans the Escherichia coli plasma membrane with its amino-terminus facing the periplasm. It is made as a precursor—the procoat—with a typical leader peptide. Mutations which destroy the basic character of the carboxy-terminal domain of procoat, a domain which is oriented towards the cytoplasm, block membrane assembly, while insertion of three lysyl residues near the carboxy terminus partially restores assembly. Thus the information specifying membrane insertion of M13 procoat protein is found in its mature region as well as the leader and is not simply decoded in an amino to carboxy direction.
