title: Assembly of LamB and OmpF in deep rough lipopolysaccharide mutants of Escherichia coli K-12.
abstract: Assembly of the OmpF and LamB proteins was kinetically retarded in deep rough lipopolysaccharide mutants of Escherichia coli K-12. OmpF assembly was affected at the step of conversion of metastable trimers to stable trimers, whereas LamB assembly was influenced both at the monomer-to-metastable trimer and metastable-to-stable trimer steps. These assembly defects were reversed in the presence of the sfaA1 and sfaB3 suppressor alleles, which were isolated by using ompF assembly mutants.
