title: Sequence analysis of mutations that prevent export of lambda receptor, an Escherichia coli outer membrane protein.
abstract: The amino-terminal signal sequence is required for initiation of transmembrane protein transfer of the Escherichia coli lambda receptor protein. Mutations leading to insertion of charged amino acids into or deletion of amino acids from the hydrophobic segment of this sequence prevent export of this outer membrane protein.
